and a distance from the cylinder shaft center to
the load application point of Lo = 8cm, find the
intersection point by extending upward from the
horizontal axis of data A where the distance
from the shaft center is 8cm, and then extending
to the side, find the allowable driving force on
the vertical axis.
Models suitable to satisfy the requirement of 100
(N) are CY1B32H or CY1B40H, CY1B40L.

Precautions on Design (2)
Cylinder Dead Weight Deflection
Vertical Operation
Intermediate Stops
When the cylinder is mounted horizontally,
deflection appears due to its own weight as
shown in the data, and the longer the stroke is,
the greater the amount of variation in the shaft
center.
The load should be guided by a ball type
bearing (LM guide, etc.). If a slide bearing is
used, sliding resistance increases due to the
load weight and load moment, which can
cause malfunction.

When stopping a load in mid-stroke using an
external stopper, etc., operate within the
operating pressure limits shown in the table

Specific product Precautions
Be sure to read before handling. Refer to pages 72 through 75 for safety instructions and actuator precautions.
Mounting
Disassembly & Maintenance
Warning
Caution
1. Take care to avoid nicks or other damage on
the outside surface of the cylinder tube.
1. Use caution as the attractive power of the
magnets is very strong.
This can lead to damage of the scraper and wear ring, which in
turn can cause malfunction.
When removing the external slider and piston slider from the
cylinder tube for maintenance, etc., handle with caution, since the
magnets installed in each slider have very strong attractive power.
2. Take care regarding rotation of the external
slider.
Rotation should be controlled by connecting it to another shaft
(linear guide, etc.).
3. Do not operate with the magnetic coupling
out of position.
In case the magnetic coupling is out of position, push the external
slider back into the correct position by hand at the end of the
stroke (or correct the piston slider with air pressure).
4. Be sure that both head covers are secured to
a mounting surface before operating the
cylinder.
Avoid operation with the external slider secured to the surface.
5. Do not apply a lateral load to the external
slider.
When a load is mounted directly to the cylinder, variations in the
alignment of each shaft center cannot be assimilated, and this
results in the generation of a lateral load that can cause
malfunction. The cylinder should be operated using a connection
method which allows for assimilation of shaft alignment variations
and deflection due to the cylinder's own weight. A drawing of a
recommended mounting is shown in Figure 2.
Guide rod
Direct connection
with bolts, etc.
Caution
1. When reattaching the head covers after
disassembly, confirm that they are tightened
securely.
When disassembling, hold the wrench flat section of one head
cover with a vise, and remove the other cover using a spanner or
adjustable angle wrench on its wrench flat section. When
retightening, first coat with Locktight (No. 542 red), and retighten
3 to 5° past the original position prior to removal.
2. Use caution when taking off the external
slider, as the piston slider will be directly
attracted to it.
When removing the external slider or piston slider from the
cylinder tube, first force the sliders out of their magnetically
coupled positions and then remove them individually while there is
no longer any holding force. If they are removed when still
magnetically coupled, they will be directly attracted to one another
and will not come apart.
3. Since the magnetic holding force can be
changed (for example, from CY1B25L to
CY1B25H), contact SMC if this is necessary.
4. Do not disassemble the magnetic
components (piston slider, external slider).
This can cause a loss of holding force and malfunction.
Rodless cylinder
Variations in the load and cylinder
shaft alignment cannot be assimilated,
resulting in malfunction.
Shaft alignment variations are assimilated
by providing clearance for the mounting
bracket and cylinder. Moreover, the mounting
bracket is extended above the cylinder shaft
center, so that the cylinder is not subjected
to moment.
Figure 1. Incorrect mounting
Figure 2. Recommended mounting
6. Use caution regarding the allowable load
weight when operating in a vertical direction.
5. When disassembling to replace the seals
and wear ring, refer to the separate
disassembly instructions.
6. Note the direction of the external slider and
piston slider.
Since the external slider and piston slider are directional for ø6,
ø10 and holding force type L, refer to the drawings below when
performing disassembly or maintenance. Put the external slider
and piston slider together, and insert the piston slider into the
cylinder tube so that they will have the correct positional
relationship as shown in Figure 3. If they align as shown in Figure
4, insert the piston slider after turning it around 180°. If the
direction is not correct, it will be impossible to obtain the specified
holding force.
The allowable load weight when operating in a vertical direction
(reference values on page 5) is determined by the model selection
method, however, if a load greater than the allowable value is
applied, the magnetic coupling may break and there is a possibility
of dropping the load. When using this type of application, contact
SMC regarding the operating conditions (pressure, load, speed,
stroke, frequency, etc.).

Cylinder Dead Weight Deflection
Vertical Operation
Max. Load Weight when Loaded Directly on Body
When the cylinder is mounted horizontally,
deflection appears due to its own weight as
shown in the data, and the longer the stroke is,
the greater the amount of variation in the shaft
center. Therefore, a connection method should
be considered which can assimilate this
deflection.
The load should be guided by a ball type
bearing (LM guide, etc.). If a slide bearing is
used, sliding resistance increases due to the
load weight and load moment, which can
cause malfunction.
When the load is applied directly to the body, it
should be no greater than the maximum
values shown in the table below.

When stopping a load having a large inertial force at the stroke end, tilting of the body and damage to
the bearings and cylinder tube may occur. (Refer to the left hand drawing below.)
As shown in the right hand drawing below, a shock absorber should be used together with the stopper,
and thrust should also be transmitted from the center of the body so that tilting will not occur.

below. Use caution, as operation when
exceeding the allowable value can result in
breaking of the magnetic coupling.

Note 1) Avoid operations where rotational torque (moment) is applied. In such a case, the use of an external guide is
recommended.
Note 2) The above reference values will be satisfied within the allowable stroke ranges, but caution is necessary,
because as the stroke becomes longer, the inclination (rotation angle) within the stroke can be expected to
increase.
Note 3) When a load is applied directly to the body, the loaded weight should be no greater than the allowable load
weights on page 14.

Auto Switch Mounting
1N⋅m: Approx.10.2kgf⋅cm
When mounting auto switches, they
should be inserted into the cylinder's
switch groove from the direction
shown in the drawing on the right.
After setting in the mounting position,
use a flat head watchmakers screw
driver to tighten the mounting
screw which is included.
Note) When tightening the auto switch mounting screw, use a
watchmakers screw driver with a handle about 5 to 6mm in
diameter.
Furthermore, the tightening torque should be approximately 0.05
to 0.1N⋅m (0.51 to 1.02kgf⋅cm). As a rule, it can be turned about
90° past the point at which tightening can be felt.

Auto Switch Specifications
(1) Switches (switch rail) can be added to the standard type (without switch rail). The switch rail
accessory type is mentioned on page 17, and can be ordered together with auto switches.
(2) Refer to the separate disassembly instructions for switch magnet installation procedures.

Specific product Precautions
Be sure to read before handling. Refer to pages 72 through 75 for safety instructions and actuator precautions.
Mounting
Disassembly & Maintenance
Warning
Caution
1. Take care to avoid nicks or other damage on the
outside surface of the cylinder tube.
1. Use caution as the attractive power of the magnets
is very strong.
This can lead to damage of the scraper and wear ring, which
in turn can cause malfunction.
When removing the external slider and piston slider from the
cylinder tube for maintenance, etc., handle with caution, since
the magnets installed in each slider have very strong attractive
power.
2. Take care regarding rotation of the external slider.
Rotation should be controlled by connecting it to another shaft
(linear guide, etc.).
3. Do not operate with the magnetic coupling out of
position.
Caution
1. Special tools are necessary for disassembly.
In case the magnetic coupling is out of position, push the
external slider back into the correct position by hand at the end
of the stroke (or correct the piston slider with air pressure).
4. The cylinder is mounted with bolts through the
mounting holes in the end covers. Be sure they are
tightened securely.
5. If gaps occur between the mounting surface and the
end covers when mounting with bolts, perform shim
adjustment using spacers, etc. so that there is no
unreasonable stress.
6. Be sure that both end covers are secured to the
mounting surface before operating the cylinder.
Avoid operation with the external slider secured to the surface.
7. Do not apply a lateral load to the external slider.
When a load is mounted directly to the cylinder, variations in
the alignment of each shaft center cannot be assimilated,
which results in the generation of a lateral load that can cause
malfunction. The cylinder should be operated using a
connection method which allows for assimilation of shaft
alignment variations and deflection due to the cylinder's own
weight. A drawing of a recommended mounting is shown in
Figure 2.

Variations in the load and cylinder
shaft alignment cannot be assimilated,
resulting in malfunction.
Shaft alignment variations are assimilated
by providing clearance for the mounting
bracket and cylinder. Moreover, the
mounting bracket is extended above the
cylinder shaft center, so that the cylinder
is not subjected to moment.
Figure 1. Incorrect mounting
Figure 2. Recommended mounting
8. Use caution regarding the allowable load weight
when operating in a vertical direction.
The allowable load weight when operating in a vertical
direction (reference values on page 14) is determined by the
model selection method, however, if a load greater than the
allowable value is applied, the magnetic coupling may break
and there is a possibility of dropping the load. When using this
type of application, contact SMC regarding the operating
conditions (pressure, load, speed, stroke, frequency, etc.).

2. Use caution when taking off the external slider, as
the piston slider will be directly attracted to it.
When removing the external slider or piston slider from the
cylinder tube, first force the sliders out of their magnetically
coupled positions and then remove them individually when
there is no longer any holding force. If they are removed when
still magnetically coupled, they will be directly attracted to one
another and will not come apart.
3. Since the magnetic holding force can be changed
(for example, from CY1R25L to CY1R25H), contact
SMC if this is necessary.
4. Do not disassemble the magnetic components
(piston slider, external slider).
This can cause a loss of holding force and malfunction.
5. When disassembling to replace the seals and wear
ring, refer to the separate disassembly instructions.
6. Note the direction of the external slider and piston
slider.
Since the external slider and piston slider are directional for
ø6, ø10 and holding force type L, refer to the drawings below
when performing disassembly or maintenance. Put the
external slider and piston slider together, and insert the piston
slider into the cylinder tube so that they will have the correct
positional relationship as shown in Figure 3. If they align as
shown in Figure 4, insert the piston slider after turning it
around 180°. If the direction is not correct, it will be impossible
to obtain the specified holding force.

Auto Switch Mounting
1N⋅m: Approx. 10.2kgf⋅cm
When mounting an auto switch, the switch mounting screw should be
screwed into a hexagon nut (M3 x 0.5) which has been inserted into
the groove of the switch rail. (Tightening torque should be about 0.05
to 0.1N⋅m {0.51 to 1.02kgf⋅cm}.)

Specific product Precautions
Be sure to read before handling. Refer to pages 72 through 75 for safety instructions and actuator precautions.
Operation
Warning
Disassembly & Maintenance
Warning
1. Use caution in the space between the plates
and the slide block.
1. Use caution as the attractive power of the
magnets is very strong.
Take sufficient care as fingers and hands, etc. may be injured
if caught while the cylinder is in operation.
When removing the external slider and piston slider from the
cylinder tube for maintenance, etc., handle with caution, since
the magnets installed in each slider have very strong
attractive power.
2. Do not apply a load to a cylinder which is
greater than the allowable value in the
selection data.
Mounting
Caution
1. Avoid operation with the external slider fixed
to a mounting surface.
The cylinder should be operated with the plates fixed to a
mounting surface.
2. Perform mounting so that the external slider
will operate through the entire stroke at the
minimum operating pressure.
If the mounting surface is not flat, the guides will be warped,
increasing the minimum operating pressure and causing
premature wear of the bearings. Therefore, mounting should
be performed so that the external slider will operate through
the entire stroke at the minimum operating pressure. A
mounting surface with a high degree of flatness is desired, but
in cases where this cannot be adaquately confirmed, shim
adjustment, etc. should be performed.
Caution
1. Use caution when taking off the external
slider, as the piston slider will be directly
attracted to it.
When removing the external slider or piston slider from the
cylinder tube, first force the sliders out of their magnetically
coupled positions and then remove them individually when
there is no longer any holding force. If they are removed when
still magnetically coupled, they will be directly attracted to one
another and will not come apart.
2. Since the magnetic holding force can be
changed (for example, from CY1S25L to
CY1S25H), contact SMC if this is necessary.
3. Do not disassemble the magnetic components
(piston slider, external slider).
This can cause a loss of holding force and malfunction.
4. When disassembling to replace the seals
and wear ring, refer to the separate
disassembly instructions.
5. Note the direction of the external slider and
piston slider.
Since the external slider and piston slider are directional for
ø6, ø10 and holding force type L, refer to the drawings below
when performing disassembly or maintenance. Put the
external slider and piston slider together, and insert the piston
slider into the cylinder tube so that they will have the correct
positional relationship as shown in Figure 1. If they align as
shown in Figure 2, insert the piston slider after turning it
around 180°. If the direction is not correct, it will be impossible
to obtain the specified holding force.

Auto Switch Mounting
IN m: Approx.10.2kgf⋅cm
When mounting an auto switch, the switch mounting screw should be screwed into a
hexagon nut (M3 x 0.5) which has been inserted into the groove of the switch rail.
(Tightening torque should be about 0.05 to 0.1N⋅m {0.51 to 1.02kgf⋅cm}.)

Specific product Precautions
Be sure to read before handling. Refer to pages 72 through 75 for safety instructions and actuator precautions.
Operation
Warning
Disassembly & Maintenance
Warning
1. Use caution in the space between the plates
and the slide block.
1. Use caution as the attractive power of the
magnets is very strong.
Take sufficient care as fingers and hands, etc. may be injured
if caught while the cylinder is in operation.
When removing the external slider and piston slider from the
cylinder tube for maintenance, etc., handle with caution, since
the magnets installed in each slider have very strong
attractive power.
2. Do not apply a load to a cylinder which is
greater than the allowable value in the
selection data.
Mounting
Caution
1. Avoid operation with the external slider fixed
to a mounting surface.
The cylinder should be operated with the plates fixed to a
mounting surface.
2. Perform mounting so that the external slider
will operate through the entire stroke at the
minimum operating pressure.
If the mounting surface is not flat, the guides will be warped,
increasing the minimum operating pressure and causing
premature wear of the bearings. Therefore, mounting should
be performed so that the external slider will operate through
the entire stroke at the minimum operating pressure. A
mounting surface with a high degree of flatness is desired, but
in cases where this cannot be adequately confirmed, shim
adjustment, etc. should be performed.
Caution
1. Use caution when taking off the external
slider, as the piston slider will be directly
attracted to it.
When removing the external slider or piston slider from the
cylinder tube, first force the sliders out of their magnetically
coupled positions and then remove them individually when
there is no longer any holding force. If they are removed when
still magnetically coupled, they will be directly attracted to one
another and will not come apart.
2. Since the magnetic holding force can be
changed (for example, from CY1S25L to
CY1S25H), contact SMC if this is necessary.
3. Do not disassemble the magnetic components
(piston slider, external slider).
This can cause a loss of holding force and malfunction.
4. When disassembling to replace the seals
and wear ring, refer to the separate
disassembly instructions.
5. Note the direction of the external slider and
piston slider.
Since the external slider and piston slider are directional for
ø6, ø10 and holding force type L, refer to the drawings below
when performing disassembly or maintenance. Put the
external slider and piston slider together, and insert the piston
slider into the cylinder tube so that they will have the correct
positional relationship as shown in Figure 1. If they align as
shown in Figure 2, insert the piston slider after turning it
around 180°. If the direction is not correct, it will be impossible
to obtain the specified holding force.

When mounting auto switches,
they should be inserted into the
cylinder's switch groove from the
direction shown in the drawing on
the right. After setting in the
mounting position, use a flat head
watchmakers screw driver to
tighten the set screw which is
included.
Auto switch
Note) When tightening the auto switch set screw
(included with the auto switch), use a
watchmakers screw driver with a handle
about 5 to 6mm in diameter. The tightening
torque should be approximately 0.05 to
0.1N⋅m (0.51 to 1.02kgf⋅cm).

Auto Switch Lead Wire Containment Groove
On models CY1H20 and CY1H25 a groove is provided on the side of the body (one side only) to
contain auto switch lead wires. This should be used for management of wiring.

Specific Product Precautions
Be sure to read before handling. Refer to pages 72 through 75 for safety instructions and actuator precautions.
Operation
Mounting
Caution
Caution
1. The interior is protected to a certain extent
by the top cover, however, when performing
maintenance, etc., take care not to cause
scratches or other damage to the cylinder
tube, slide table or linear guide by striking
them or placing objects on them.
The bore and exterior of tubes are manufactured to precise
tolerances, so that even a slight deformation can cause
malfunction.
2. Since the slide table is supported by
precision bearings, strong impacts or large
moment, etc. should not be applied when
mounting work pieces.
3. Mounting of the cylinder body
The body is mounted using the square nuts, which are
included, in the two T-grooves on the bottom of the body.
Refer to the table below for mounting bolt dimensions and
fastening torque.

1. The unit can be used with a direct load
within the allowable range, but when
connecting to a load which has an external
guide mechanism, careful alignment is
necessary.
Since variation of the shaft center increases as the stoke
becomes longer, a connection method should be devised
which can assimilate this displacement.
2. Since the guide is adjusted at the time of
shipment, unintentional movement of the
adjustment setting should be avoided.
3. This unit can be operated without
lubrication. If lubrication is performed, use
class 1 turbine oil (without additives) ISO
VG32. (Machine oil and spindle oil cannot be
used.)
4. Contact SMC before operating in an
environment where there will be contact
with cutting chips, dust (paper scraps,
thread scraps, etc.) or cutting oil (gas oil,
water, salt water, etc.).
5. Do not operate with the magnetic coupling
out of position.
In case the magnetic coupling is out of position, push the
external slider back into the correct position by hand at the
end of the stroke (or correct the piston slider with air
pressure).
Square nut
6. Do not disassemble the magnetic components
(piston slider, external slider).
t
l
This can cause a loss of holding power and malfunction.
4. Stroke adjustment
Stroke adjustment on one side of 15mm ( CY1H10,15, 20) or
30mm (CY1H25, CY1HT25, CY1HT32) can be performed with
the adjustment bolt, but when the amount of adjustment
exceeds 3mm, the magnetic coupling may be broken
depending on the operating conditions. Therefore, operation
should confirm to the intermediate stop conditions on page 50.
Moreover, the stroke should not be adjusted by moving the
stopper, as this can cause damage to the cylinder.

The above auto switches do not have built-in contact protection circuits.
1. The operating load is an induction load.
2. The length of wiring to the load is 5m or more.
3. The load voltage is 100V or 200VAC.
A contact protection box should be used in any of the above cases,
as the life of the contacts may be reduced. (They may stay on
continuously.)
Since this effect is especially strong in the case of type D-A72(H), a
contact protection box should always be used, regardless of the type
of load or length of wiring.

Because there is no current

will not increase when
turned OFF, but due to the
number of switches in the

lights will sometimes get
dark or not light up,
because of dispersion and
reduction of the current
flowing to the switches.

Auto Switch Hysteresis
The distance from the position at which movement of the external slider
turns on an auto switch, to the point at which reverse movement turns off
the switch is called hysteresis. This hysteresis is included in part (one
side) of the operating range.

Note 1) Dimension F provides a clearance of 1mm between the body and the floating joint, but does not consider dead weight deflection of the cylinder tube, etc. When put into
operation, an appropriate value should be set which considers dead weight deflection and alignment variations with respect to the other axis. (Refer to the dead weight
deflection table on page 5.)
Note 2) Use caution when attached from the top and operated at or above dimension R (3mm or more for ø6, ø10), because the end of the screw will contact the body, and floating
cannot be maintained in some cases.

observe ISO 4414 Note 1), JIS B 8370 Note 2) and other safety practices.
Caution : Operator error could result in injury or equipment damage.
Warning :
Operator error could result in serious injury or loss of life.
Danger :
In extreme conditions, there is a possible result of serious injury or loss of life.
Note 1) ISO 4414 : Pneumatic fluid power -- Recommendations for the application of equipment to transmission and
control systems.
Note 2) JIS B 8370 : Pneumatic system axiom.
Warning
1 The compatibility of pneumatic equipment is the responsibility of the person
who designs the pneumatic system or decides its specifications.
Since the products specified here are used in various operating conditions, their compatibility for the
specific pneumatic system must be based on specifications or after analysis and/or tests to meet your
specific requirements.
2 Only trained personnel should operate pneumatically operated machinery and
equipment.
Compressed air can be dangerous if an operator is unfamiliar with it. Assembly, handling or repair of
pneumatic systems should be performed by trained and experienced operators.
3 Do not service machinery/equipment or attempt to remove components until
safety is confirmed.
1.Inspection and maintenance of machinery/equipment should only be performed after confirmation of
safe locked-out control positions.
2.When equipment is to be removed, confirm the safety process as mentioned above. Cut the supply
pressure for this equipment and exhaust all residual compressed air in the system.
3.Before machinery/equipment is restarted, take measures to prevent shooting-out of cylinder piston rod,
etc. (Bleed air into the system gradually to create back-pressure.)
4 Contact SMC if the product is to be used in any of the following conditions:
1.Conditions and environments beyond the given specifications, or if product is used outdoors.
2.Installation on equipment in conjunction with atomic energy, railway, air navigation, vehicles, medical
equipment, food and beverages, recreation equipment, emergency stop circuits, press applications, or
safety equipment.
3.An application which has the possibility of having negative effects on people, property, or animals,
requiring special safety analysis.

CY1
Actuator Precautions 1
Series
Be sure to read before handling.
Precautions on design
Warning
1. There is a possibility of dangerous sudden
action by air cylinders if sliding parts of
machinery are twisted due to external
forces, etc.
In such cases, human injury may occur; e.g., by catching hands or
feet in the machinery, or damage to the machinery itself may occur.
Therefore, the machine should be designed to avoid such dangers.
2. A protective cover is recommended to minimize the risk of personal injury.
If a stationary object and moving parts of a cylinder are in close
proximity, personal injury may occur. Design the structure to avoid
contact with the human body.
3. Securely tighten all stationary parts and
connected parts so that they will not
become loose.
When a cylinder operates with high frequency or a cylinder is
installed where there is a lot of vibration, ensure that all parts
remain secure.
Selection
Warning
1. Check the specifications.
The products advertised in this catalog are designed according to
use in industrial compressed air systems. If the products are used
in conditions where pressure, temperature, etc., are out of specification, damage and/or malfunction may be caused. Do not use
in these conditions.
Consult SMC if you use a fluid other than compressed air.
2. Intermediate stops.
When intermediate stopping of a cylinder piston is performed with
a 3 position closed center type directional control valve, it is difficult to achieve stopping positions as accurate and minute as with
hydraulic pressure, due to the compressibility of air.
Furthermore, since valves and cylinders, etc. are not guaranteed
for zero air leakage, it may not be possible to hold a stopped position for an extended period of time. Contact SMC in case it is necessary to hold a stopped position for an extended period.
Caution
4. A deceleration circuit or shock absorber,
etc., may be required.
1. Operate within the limits of the maximum
usable stroke.
When a driven object is operated at high speed or the load is
heavy, a cylinder’s cushion will not be sufficient to absorb the
shock. Install a deceleration circuit to reduce the speed before
cushioning, or install an external shock absorber to relieve the
shock. In this case, the rigidity of the machinery should also be
examined.
Refer to the selection procedures for the type of air cylinder to be
used for the maximum usable stroke.
5. Consider a possible drop in operating pressure due to a power outage, etc.
When a cylinder is used in a clamping mechanism, there is a danger of work dropping if there is a decrease in clamping force due
to a drop in circuit pressure caused by a power outage, etc.
Therefore, safety equipment should be installed to prevent damage to machinery and human injury. Suspension mechanisms and
lifting devices also require consideration for drop prevention.
2. Operate the piston within a range such that
collision damage will not occur at the end of
the stroke.
Operate within a range such that damage will not occur when the
piston having inertial force stops by striking the cover at the stroke
end. Refer to the cylinder type selection procedure for the range
within which damage will not occur.
3. Use a speed controller to adjust the cylinder
drive speed, gradually increasing from a low
speed to the desired speed setting.
6. Consider a possible loss of power source.
Measures should be taken to protect against human injury and
equipment damage in the event that there is a loss of power to
equipment controlled by air pressure, electricity or hydraulics, etc.
7. Design circuitry to prevent sudden lurching
of driven objects.
When a cylinder is driven by an exhaust center type directional
control valve or when starting up after residual pressure is
exhausted from the circuit, etc., the piston and its driven object will
lurch at high speed if pressure is applied to one side of the cylinder because of the absence of air pressure inside the cylinder.
Therefore, equipment should be selected and circuits designed to
prevent sudden lurching, because there is a danger of human
injury and/or damage to equipment when this occurs.
8. Consider emergency stops.
Design so that human injury and/or damage to machinery and
equipment will not be caused when machinery is stopped by a
safety device under abnormal conditions, a power outage or a
manual emergency stop.
9. Consider the action when operation is
restarted after an emergency stop or abnormal stop.
Design the machinery so that human injury or equipment damage
will not occur upon restart of operation. When the cylinder has to
be reset at the starting position, install manual safety equipment.
73
CY1
Actuator Precautions 2
Series
Be sure to read before handling.
Mounting
Caution
Caution
1. Align carefully when connecting to a load
having an external guide mechanism.
Since variation of the shaft center becomes greater as the stroke
becomes longer, a connection method (floating mechanism)
should be considered which can assimilate this variation.
Moreover, consideration should be given to the exclusive floating
joint (XC 57), which has been created for series CY1B and CY1R.
2. When an external guide is used, connect the
external slider and the load in such a way
that there is no interference at any point
within the stroke.
3. Do not scratch or dent the sliding parts of
the cylinder tube by striking or grasping
them with other objects.
Cylinder bores are manufactured to precise tolerances, so that
even a slight deformation may cause faulty operation.
4. Do not use until you verify that the equipment can operate properly.
After mounting, repair or modification, etc., connect the air supply
and electric power, and then confirm proper mounting by means
of appropriate function and leak inspections.
5. Instruction manual.
The product should be mounted and operated after thoroughly
reading the manual and understanding its contents.
Keep the instruction manual where it can be referred to as needed.
Piping
Caution
1. Preparation before piping.
Before piping is connected, it should be thoroughly blown out with
air (flushing) or washed to remove cutting chips, cutting oil and
other debris from inside the pipe.
2. Wrapping of pipe tape.
When connecting pipes and fittings, etc., be certain that cutting
chips from the pipe threads and sealing material do not get inside
the piping.
Also, when pipe tape is used, leave 1.5 to 2 thread ridges exposed
at the end of the pipe/fitting.

Lubrication
ds
1. Lubrication of cylinder.
The cylinder has been lubricated for life at the factory and can be
used without any further lubrication.
However, in the event that it will be lubricated, use class 1 turbine
oil (with no additives) ISO VG32.
Stopping lubrication later may lead to malfunction due to the loss
of the original lubricant. Therefore, lubrication must be continued
once it has been started.
Air Supply
Warning
1. Use clean air.
If compressed air includes chemicals, synthetic oils containing
organic solvents, salt or corrosive gases, etc., it can cause damage or malfunction.
Caution
1. Install air filters.
Install air filters at the upstream side of valves. The filtration
degree should be 5µm or less.
2. Install an air dryer, after cooler, etc.
Air that includes excessive condensate may cause malfunction of
valves and other pneumatic equipment. To prevent this, install an
air dryer, after cooler, etc.
3. Use the product within the specified range
of fluid and ambient temperature.
Take measures to prevent freezing, since moisture in circuits will
be frozen under 5°C, and this may cause damage to seals and
lead to malfunction.
Refer to SMC’s “Air Cleaning Equipment” catalog for further
details on compressed air quality.
CY1
Actuator Precautions 3
Series
Be sure to read before handling.
Operating Environment
Warning
1. Do not use in environments where there is a
danger of corrosion.
Refer to the construction drawings regarding cylinder materials.
2. In dirty areas, such as dusty locations or
where water, oil, etc. splash on the equipment, take suitable protective measures.
Contact SMC in cases where dust or water, etc. will be scattered
throughout the area.
Maintenance
Warning
1. Maintenance should be done according to
the procedure indicated in the operating
manual.
If handled improperly, malfunction and damage of machinery or
equipment may occur.
2. Machine maintenance, and supply and
exhaust of compressed air.
When machinery is serviced, first check measures to prevent
dropping of driven objects and run-away of equipment, etc. Then
cut off the supply pressure and electric power, and exhaust all
compressed air from the system.
When machinery is restarted, check that operation is normal with
actuators in the proper positions.
Caution
1. Drain flushing.
Remove condensate from air filters regularly. (Refer to specifications.)

CY1
Auto Switch Precautions 1
Series
Be sure to read before handling.
Design & Selection
Warning
Warning
1. Confirm the specifications.
Read the specifications carefully and use this product appropriately. The product may be damaged or malfunction if it is used
outside the range of specifications of current load, voltage, temperature or impact.
2. Take precautions when multiple cylinders
are used close together.
When multiple auto switch cylinders are used in close proximity,
magnetic field interference may cause the switches to malfunction. Maintain a minimum cylinder separation of 40mm. (When the
allowable separation is indicated for each cylinder series, use the
specified value.)
3. Pay attention to the length of time that a
switch is ON at an intermediate stroke position.
When an auto switch is placed at an intermediate position of the
stroke and a load is driven at the time the piston passes, the auto
switch will operate, but if the speed is too great the operating time
will be shortened and the load may not operate properly. The maximum detectable piston speed is:
Auto switch operating range (mm)
V(mm/s) = ____________________________ x 1000
Time load applied (ms)
In cases of high piston speed, the use of an auto switch (F7NT)
with a built-in OFF delay timer (approx. 200ms) makes it possible
to extend the load operating time.
• In the same way, when operating under a specified voltage,
although an auto switch may operate normally, the load may not
operate. Therefore, the formula below should be satisfied after
confirming the minimum operating voltage of the load.
Supply
Minimum operating
– Internal voltage >
voltage
voltage of load
drop of switch
2) If the internal resistance of a light emitting diode causes a problem, select a switch without an indicator light (Model A80, A80H,
A90 and Z80).
<Solid state switch>
3) Generally, the internal voltage drop will be greater with a 2 wire
solid state auto switch than with a reed switch. Take the same precautions as in 1).
Also, note that a 12VDC relay is not applicable.
6. Pay attention to leakage current.
<Solid state switch>
With a 2 wire solid state auto switch, current (leakage current)
flows to the load to operate the internal circuit even when in the
OFF state.
Operating current of load (OFF condition) > Leakage current
If the criteria given in the above formula are not met, it will not
reset correctly (stays ON). Use a 3 wire switch if this specification
will not be satisfied.
Moreover, leakage current flow to the load will be “n” times larger
when “n” auto switches are connected in parallel.
4. Wiring should be kept as short as possible.
<Reed switch>
As the length of the wiring to a load gets longer, the rush current
at switching ON becomes greater, and this may shorten the product’s life. (The switch will stay ON all the time.)
1) For an auto switch without a contact protection circuit, use a contact protection box when the wire length is 5m or longer.
2) Even if an auto switch has a built-in contact protection circuit,
when the wiring is more than 30m long, it is not able to adequately
absorb the rush current and its life may be reduced. It is again
necessary to connect a contact protection box in order to extend
its life. Please contact SMC in this case.
<Solid state switch>
3) Although wire length should not affect switch function, use a wire
100m or shorter.
5. Take precautions for the internal voltage
drop of the switch.
<Reed switch>
1) Switches with an indicator light (Except A76H, A96 and Z76)
• If auto switches are connected in series as shown below, take note
that there will be a large voltage drop because of internal resistance in the light emitting diode. (Refer to internal voltage drop in
the auto switch specifications.)
[The voltage drop will be “n” times larger when “n” auto switches
are connected.]
Even though an auto switch operates normally, the load may not
operate.
Load
76
7. Do not use a load that generates surge voltage.
<Reed switch>
If driving a load such as a relay that generates a surge voltage,
use a switch with a built-in contact protection circuit or use a contact protection box.
<Solid state switch>
Although a zener diode for surge protection is connected at the
output side of a solid state auto switch, damage may still occur if
the surge is applied repeatedly. When a load, such as a relay or
solenoid, which generates surge is directly driven, use a type of
switch with a built-in surge absorbing element.
8. Cautions for use in an interlock circuit.
When an auto switch is used for an interlock signal requiring high
reliability, devise a double interlock system to avoid trouble by providing a mechanical protection function, or by also using another
switch (sensor) together with the auto switch. Also perform periodic maintenance and confirm proper operation.
9. Ensure sufficient clearance for maintenance
activities.
When designing an application, be sure to allow sufficient clearance for maintenance and inspections.
CY1
Auto Switch Precautions 2
Series
Be sure to read before handling.
Mounting & Adjustment
Wiring
Warning
Warning
1. Do not drop or bump.
Do not drop, bump or apply excessive impacts (300m/s² or more
for reed switches and 1000m/s² or more for solid state switches)
while handling.
Although the body of the switch may not be damaged, the inside
of the switch could be damaged and cause a malfunction.
2. Do not carry a cylinder by the auto switch
lead wires.
Never carry a cylinder by its lead wires. This may not only cause
broken lead wires, but it may cause internal elements of the
switch to be damaged by the stress.
3. Mount switches using the proper fastening
torque.
When a switch is tightened beyond the range of fastening torque,
the mounting screws, mounting bracket or switch may be damaged. On the other hand, tightening below the range of fastening
torque may allow the switch to slip out of position. ( Refer to switch
mounting for each series regarding switch mounting, moving, and
fastening torque, etc. .)
4. Mount a switch at the center of the operating
range.
Adjust the mounting position of an auto switch so that the piston
stops at the center of the operating range (the range in which a
switch is ON).
(The mounting position shown in a catalog indicates the optimum
position at stroke end.) If mounted at the end of the operating
range (around the borderline of ON and OFF), operation will be
unstable.
Wiring
Warning
5. Do not allow short circuit of loads.
<Reed switch>
If the power is turned ON with a load in a short circuit condition,
the switch will be instantly damaged because of excess current
flow into the switch.
<Solid state switch>
Model D-F9, F-9W and all models of PNP output type switches do not have built-in short circuit prevention circuits. If loads are
short circuited, the switches will be instantly damaged.
Take special care to avoid reverse wiring with the brown (red)
power supply line and the black (white) output line on 3 wire type
switches.
6. Avoid incorrect wiring.
<Reed switch>
A 24VDC switch with indicator light has polarity. The brown lead
wire or terminal No. 1 is (+), and the blue lead wire or terminal No.
2 is (–).
[In the case of model D-97, the side without indicator is (+), and
the black line side is (–).]
1) If connections are reversed, a switch will operate, however, the
light emitting diode will not light up.
Also note that a current greater than that specified will damage a
light emitting diode and it will no longer operate.
Applicable models: D-A73, A73H, A73C, Z73, D-A93
<Solid state switch>
1) If connections are reversed on a 2 wire type switch, the switch will
not be damaged if protected by a protection circuit, but the switch
will always stay in an ON state. However, it is still necessary to
avoid reversed connections, since the switch could be damaged
by a load short circuit in this condition.
2) If connections are reversed (power supply line + and power supply line –) on a 3 wire type switch, the switch will be protected by
a protection circuit. However, if the power supply line (+) is connected to the blue (black) wire and the power supply line (–) is
connected to the black (white) wire, the switch will be damaged.
1. Avoid repeatedly bending or stretching lead
wires.
Broken lead wires will result from applying bending stress or
stretching force to the lead wires.
2. Be sure to connect the load before power is
applied.
<2 wire type>
If the power is turned ON when an auto switch is not connected to
a load, the switch will be instantly damaged because of excess
current.
3. Confirm proper insulation of wiring.
Be certain that there is no faulty wiring insulation (contact with
other circuits, ground fault, improper insulation between terminals,
etc.). Damage may occur due to excess current flow into a switch.
4. Do not wire with power lines or high voltage
lines.
Wire separately from power lines or high voltage lines, avoiding
parallel wiring or wiring in the same conduit with these lines.
Control circuits, including auto switches, may malfunction due to
noise from these other lines.
∗ Lead wire color changes
Lead wire colors of SMC switches and related products have been
changed in order to meet NECA (Nippon Electric Control
Equipment Industries Association) Standard 0402 for production
beginning September, 1996 and thereafter. Please refer to the
tables provided.
Special care should be taken regarding wire polarity during the
time that the old colors still coexist with the new colors.

Auto Switch Precautions 3
Series
Be sure to read before handling.
Operating Environment
Warning
1. Never use in an atmosphere of explosive
gases.
The structure of auto switches is not intended to prevent explosion. Never use in an atmosphere with an explosive gas since this
may cause a serious explosion.
2. Do not use in an area where a magnetic field
is generated.
Auto switches will malfunction or magnets inside cylinders will
become demagnetized. (Consult SMC regarding the availability of
a magnetic field resistant auto switch.)
3. Do not use in an environment where the
auto switch will be continually exposed to
water.
Although switches satisfy the IEC standard IP67 structure (JIS C
0920: anti-immersion structure), do not use switches in applications where continually exposed to water splash or spray. Poor
insulation or swelling of the potting resin inside switches may
cause malfunction.
4. Do not use in an environment with oil or
chemicals.
Consult SMC if auto switches will be used in an environment with
coolant, cleaning solvent, various oils or chemicals. If auto switches are used under these conditions for even a short time, they
may be adversely affected by improper insulation, malfunction
due to swelling of the potting resin, or hardening of the lead wires.
5. Do not use in an environment with temperature cycles.
Consult SMC if switches are used where there are temperature
cycles other than normal temperature changes, as they may be
adversely affected.
6. Do not use in an environment where there is
excessive impact shock.
<Reed switch>
When excessive impact (300m/s2 or more) is applied to a reed
switch during operation, the contact point will malfunction and
generate or cut off a signal momentarily (1ms or less). Consult
SMC regarding the need to use a solid state switch depending
upon the environment.
7. Do not use in an area where surges are generated.
<Solid state switch>
When there are units (solenoid type lifter, high frequency induction furnace, motor, etc.) which generate a large amount of surge
in the area around cylinders with solid state auto switches, this
may cause deterioration or damage to the switch. Avoid sources
of surge generation and disorganized lines.
8. Avoid accumulation of iron powder or close
contact with magnetic substances.
When a large amount of ferrous powder such as machining chips
or spatter is accumulated, or a magnetic substance (something
attracted by a magnet) is brought into close proximity with an auto
switch cylinder, it may cause the auto switch to malfunction due to
a loss of the magnetic force inside the cylinder.
78
Maintenance
Warning
1. Perform the following maintenance periodically in order to prevent possible danger
due to unexpected auto switch malfunction.
1) Secure and tighten switch mounting screws.
If screws become loose or the mounting position is dislocated,
retighten them after readjusting the mounting position.
2) Confirm that there is no damage to lead wires.
To prevent faulty insulation, replace switches or repair lead wires,
etc., if damage is discovered.
3) Confirm the lighting of the green light on the 2 color indicator type
switch.
Confirm that the green LED is on when stopped at the established position. If the red LED is on, the mounting position is not
appropriate. Readjust the mounting position until the green LED
lights up.
Other
Warning
1. Consult SMC concerning water resistance,
elasticity of lead wires, and usage at welding
sites, etc.
