New air cushion mechanism
Free-mounting cylinder Series CU now
employs an air cushion mechanism.
Extended dimensions (compared to the standard
CU models) are hardly noticeable.

Unique air cushion construction requires no cushion ring.
Elimination of the cushion ring used in conventional type air cushions has made it
possible to reduce the overall length of the cylinder while retaining all the advantages of
a compact profile.

q When the piston is retracting, air is exhausted
through both A and A' until piston seal H
passes air passage A.

w After piston seal H has passed air passage A,
air is exhausted only through A'. The section
marked with slanted lines becomes a cushion
chamber, and an air cushion effect is achieved.
e When air is supplied for the piston extension,
the check valve opens and the piston extends
with no delay.
Reduced stroke end impact and noise:
New standards to meet consumer demand.
Free-mounting
3 types of mounting orientations can be accommodated depending on the installation conditions.
Axial mounting (tapped holes)
Vertical mounting (body through holes)
Lateral mounting (body through holes)
Approximately 2.4 times of allowable kinetic energy
(Compared to the old Series CU with rubber bumper)
Improved sound insulation
(Reduced impact noise at the stroke end)

cushion type cylinders are less likely to be affected by
pressure fluctuations, and therefore better able to
achieve a stable and smooth stroke.

Caution – Proximity Installation
When free-mounting cylinders equipped with D-A9
or D-F9 type auto switches are used, be sure to
provide an extra clearance in addition to what is
suggested in the table at right. If the distance between
two cylinders is less than the noted value, auto
switches may malfunction. When for some reason you
cannot avoid installing cylinders closer than the
required clearance, install a steel plate or magnetic
shield plate (MU-SO25) on the side of the cylinder
facing the auto switches to shield them. (Contact SMC
for details.) Auto switches may malfunction if a
shielding plate is not used.

Load
<Solid state>
When two switches
are connected in
parallel, a malfunction may occur because the load voltage will increase
when in the OFF
state.
Load
Load voltage at OFF = Leakage
current x 2 pcs. x impedance
= 1mA x 2 pcs. x 3kΩ
= 6V
Example: Load impedance is 3kΩ
Leakage current from switch is 1mA
<Reed switch>
Because there is no current
leakage, the load voltage will
not increase when turned
OFF. However, depending
on the number of switches in
the ON state, the indicator
lights may sometimes grow
dim or not light up because
of the dispersion and reduction of the current flowing to
the switches.

Note 1) ISO 4414: Pneumatic fluid power -- Recommendations for the application of equipment to transmission and control
systems.
Note 2) JIS B 8370: General Rules for Pneumatic Equipment
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 with 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

Actuator Precautions 1
Be sure to read before handling.
Design
Warning
Design
Warning
1. There is a danger of sudden or erratic action
by cylinders if sliding parts of machinery are
twisted and changes in forces occur.
9. Consider the action when operation is restarted after an emergency stop or an abnormal stop.
In such cases, bodily injury may occur, e.g., by catching hands
or feet in the machinery, or damage to the machinery itself may
occur. Therefore, the machinery should be adjusted to operate
smoothly and designed to prevent such dangers.
Design machinery so that bodily injury or equipment damage
will not occur upon restart of operation.
When the cylinder has to be reset at the starting position, install
safe manual control equipment.
2. A protective cover is recommended to minimize the risk of personal injury.
If a driven object and moving parts of a cylinder pose a serious
danger of bodily injury, 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.
Especially when a cylinder operates with high frequency or is
installed where there is a lot of vibration, ensure that all parts
remain secure.
4. A deceleration circuit or shock absorber may
be required.
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
impact. Install a deceleration circuit to reduce the speed before
cushioning, or install an external shock absorber to relieve the
impact. In this case, the rigidity of the machinery should also be
examined.
5. Take into account a possible drop in operating pressure due to a power outage.
When a cylinder is used as a clamping mechanism, there is a
danger of work pieces dropping if there is a decrease in
clamping force due to a drop in circuit pressure caused by a
power outage. Therefore, safety equipment should be installed
to prevent damage to machinery and bodily injury. Suspension
mechanisms and lifting devices also require drop prevention
measures.
6. Take into account a possible loss of power
source.
Measures should be taken to protect against bodily injury and
equipment damage in the event that there is a loss of power to
equipment controlled by air pressure, electricity, or hydraulics.
7. Design circuitry to prevent sudden lurching
of driven objects.
Take special care when a cylinder is operated by an exhaust
center type directional control valve or when it is starting up
after residual pressure is exhausted from the circuit. 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 of the danger of bodily injury, particularly to limbs,
and/or damage to equipment when this occurs.
8. Take into account emergency stops.
Design the system so that bodily injury and/or damage to
machinery and equipment will not occur when machinery is
stopped by a manual emergency stop or a safety device
triggered by abnormal conditions.
13
Selection
Warning
1. Confirm the specifications.
The products featured in this catalog are designed for use in
industrial compressed air systems. If the products are used in
conditions where pressure and/or temperature are outside the
range of specifications, damage and/or malfunctions may
occur. Do not use in these conditions. (Refer to specifications.)
Consult with SMC if fluid other than compressed air to be used.
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 accurately and
precisely as with hydraulic pressure due to the compressibility
of air.
Furthermore, since valves and cylinders 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
1. Operate within the limits of the maximum
usable stroke.
The piston rod will be damaged if operated beyond the maximum stroke. Operate within the standard stroke range.
2. Operate the piston in such a way that collision
damage will not occur at the stroke end.
3. Use a speed controller to adjust the cylinder
drive speed, gradually increasing from a low
speed to the desired speed setting.
Series CU
Actuator Precautions 2
Be sure to read before handling.
Mounting
Cushion
Caution
Caution
1. Be certain to align the rod center of the piston
axis with the load and direction of movement
when connecting.
When a cylinder is not properly aligned, the rod and tube may
be twisted. This can cause wear on areas such as the inner
tube surface, bushings, rod surface, seals, and cause damage
to these areas.
2. When an external guide is used, connect the
piston rod end and the load in such a way
that there is no interference at any point
within the stroke.
3. Do not scratch or gouge the cylinder tube or
the sliding parts of the piston rod 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.
Also, scratches or gouges in the piston rod may lead to
damaged seals and cause air leakage.
4. Prevent the sticking (through friction) of
rotating parts.
Prevent the sticking of rotating parts (pins etc.) by applying
grease.
5. Do not use until you can verify that equipment
can operate properly.
1. Readjust using the cushion needle.
Cushion needles are fully closed at the time of shipment. When
the cylinder is put into service, the cushion needles should be
readjusted based on factors such as the size of the load and
the operating speed. When the cushion needles are turned
clockwise, restriction of the air flow becomes greater and thus
the cushion effect also increases.
2. Do not operate with the cushion needles fully
closed.
3. Adjust the cushion needles by gradually
opening from the closed condition to a desired cushion speed.
Lubrication
Caution
1. Lubrication of non-lube type cylinder
The cylinder is lubricated for life at the factory and can be used
without any further lubrication.
However, in the event that the cylinder is lubricated additionally,
be sure to use class 1 turbine oil (with no additives) ISO VG32.
Stopping lubrication later may lead to malfunctions because the
new lubricant will cancel out the original lubricant. Therefore,
lubrication must be continued once it has been started.
Following mounting, repairs, or conversions, verify correct
mounting by conducting suitable function and leakage tests
after piping and power connections have been made.
6. 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 readily referred to
as needed.
Piping
Warning
1. Use clean air.
Do not use compressed air containing chemicals, synthetic oils
containing organic solvents, salt, or corrosive gases, as this can
cause damage or malfunctions.
Caution
1. Install air filters.
Caution
1. Preparation before piping
Before piping is connected, it should be thoroughly flushed out
with air or water to remove chips, cutting oil, and other debris.
2. Wrapping of sealant tape
When screwing together pipes and fittings, be certain that chips
from the pipe threads and sealing material do not get inside the
piping.
Also, when sealant tape is used, leave 1.5 to 2 thread ridges
exposed at the end of the threads.

Air that includes excessive drainage or condensate may cause
malfunction of valves and other pneumatic equipment. To
prevent this, install an after-cooler, air dryer, or water separator
(Drain Catch).
3. Use the product within the specified range of
fluid and ambient temperature.
Take measures to prevent freezing when below 5°C, since
moisture in circuits can freeze and cause damage to seals and
lead to malfunctions.

Actuator Precautions 3
Be sure to read before handling.
Operating Environment
Warning
1. Do not use in environments where there is a
danger of corrosion.
2. In dusty conditions or where water or oil
splashing is a regular occurrence, protect the
rod by installing a rod cover.
3. When using auto switches, do not operate in
an environment where there are strong
magnetic fields.
Maintenance
Warning
1. Perform maintenance inspection and service
according to the procedures indicated in the
instruction manual.
Improper handling and maintenance may cause malfunctioning
and damage of machinery or equipment to occur.
2. Removal of components and supply/exhaust
of compressed air
Before any machinery or equipment is removed, first ensure
that the appropriate measures are in place to prevent the fall or
erratic movement of driven objects and equipment. Then cut off
the electric power and reduce the pressure in the system to
zero.
When machinery is restarted, proceed with caution after
confirming that appropriate measures are in place to prevent
cylinders from lurching.
Caution
1. Filter drainage
Drain out condensate from air filters regularly.

Series CU
Auto Switch Precautions 1
Be sure to read before handling.
Design and Selection
Warning
1. Confirm the specifications.
Read the specifications carefully and use the product appropriately. The product may be damaged or malfunction if it is used
outside the range of specifications for load current, voltage,
temperature or impact.
2. Take precautions when multiple cylinders are
used close together.
When two or more auto switch cylinders are lined up in close
proximity to each other, magnetic field interference may cause
the switches to malfunction. Maintain a minimum cylinder
separation of 40mm. (When the allowable interval is specified
for each cylinder series, use the indicated value.)
3. Monitor 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:
V(mm/s) =
Auto switch operating range (mm)
Load operating time (ms)
x 1000
4. Keep wiring as short as possible.
• Similarly, when operating below a specified voltage, it is
possible that the load may be ineffective even though the
auto switch function is normal. Therefore, the formula
below should be satisfied after confirming the minimum
operating voltage of the load.
Supply voltage –
Internal voltage
Minimum operating
drop of switch > voltage of load
2) If the internal resistance of a light emitting diode causes a
problem, select a switch without an indicator light (D-A90, DA90V).
<Solid state switches>
3) Generally, the internal voltage drop will be greater with a 2wire solid state auto switch than with a reed switch. Take the
same precautions as in 1) above.
Also, note that a 12VDC relay is not applicable.
6. Monitor leakage current.
<Solid state switches>
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.
If the condition given in the below formula is not met, the switch
will not reset correctly (it stays on).
Current to operate load (off condition) > Leakage current
<Reed switches>
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.)
Use a contact protection box when the wire length is 5m or
longer.
<Solid state switches>
Although wire length should not affect switch function, use a
wire that is 100m or shorter.
5. Monitor the internal voltage drop of the switch.
<Reed switches>
1) Switches with an indicator light (except D-A96, D-A96V)
• 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 diodes. (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
Use a 3-wire switch if this condition cannot be satisfied.
Moreover, leakage current flow to the load will be “n” times
larger when “n” auto switches are connected in parallel.
7. Do not use a load that generates surge voltage.
<Reed switches>
If driving a load that generates surge voltage, such as a relay,
use a switch with a built-in contact protection circuit or a contact
protection box.
<Solid state switches>
Although a zener diode for surge protection is connected at the
output side of a solid state auto switch, damage may still occur
if a surge is applied repeatedly. When directly driving a load
which generates surge, such as a relay or solenoid valve, 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 safeguard
against malfunctions by providing a mechanical protection
function, or by also using another switch (sensor) together with
the auto switch.
Also, perform periodic maintenance inspections 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.
16
Series CU
Auto Switch Precautions 2
Be sure to read before handling.
Mounting and Adjustment
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 tightening
torque.
When a switch is tightened beyond the range of tightening
torque, the mounting screws, mounting bracket, or switch may
be damaged.
On the other hand, tightening below the range of tightening
torque may allow the switch to slip out of position.
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 positions shown in the
catalog indicate the optimum position at the stroke end.) If
mounted at the end of the operating range (around the
borderline of on and off), the operation will be unstable.
Wiring
Warning
1. Avoid repeatedly bending or stretching lead
wires.
Broken lead wires will result from repeatedly 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 (such as
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 in conjunction 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 containing auto switches may malfunction due
to noise from these other lines.
17
Wiring
5. Do not allow short circuiting of loads.
<Reed switches>
If the power is turned on with a load in a short circuited
condition, the switch will be instantly damaged because of
excess current flow into the switch.
<Solid state switches>
D-F9(V), D-F9W(V) and all models of PNP output type
switches do not have built-in short circuit protection circuits. If
loads are short circuited, the switches will be instantly
damaged, as in the case of reed switches.
∗ 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 switches>
A 24VDC switch with indicator light has polarity. The brown [red]
lead wire is (+), and the blue [black] lead wire is (–).
1) If connections are reversed, the switch will still operate, but
the light emitting diode will not light up.
Also note that a current greater than the maximum specified
one will damage a light emitting diode and make it
inoperable.
Applicable models: D-A93, D-A93V
<Solid state switches>
1) Even if connections are reversed on a 2-wire type switch, the
switch will not be damaged because it is protected by a
protection circuit, but it will remain in a normally 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) Even if (+) and (–) power supply line connections are
reversed on a 3-wire type switch, the switch will still 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.
∗ Lead wire color changes
Lead wire colors of SMC switches have been changed in order to
meet NECA 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
Be sure to read before handling.
Operating Environment
Warning
1. Never use in the presence of explosive gases.
The construction of our auto switches does not make them
explosionproof. Never use them in the presence of an explosive
gas, as 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 if used in such an environment.
(Consult with SMC regarding the availability of magnetic field
resistant auto switches.)
3. Do not use in an environment where the auto
switch will be continually exposed to water.
Switches satisfy IEC standard IP67 construction (JIS C0920:
watertight construction). Nevertheless, they should not be used
in applications where they are continually exposed to water
splash or spray. This may cause deterioration of the insulation
or swelling of the potting resin inside switches and may lead to
a malfunction.
Maintenance
Warning
1. Perform the following maintenance inspection and services periodically in order to prevent possible danger due to unexpected auto
switch malfunction.
1) Securely tighten switch mounting screws.
If screws become loose or the mounting position is
dislocated, retighten screws securely 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 if damage is discovered.
3) Confirm that the green light on the 2-color indicator type
switch lights up.
Confirm that the Green LED is ON when stopped at the set
position. If the Red LED is ON when stopped at the set
position, the mounting position is not appropriate. Readjust
the mounting position until the Green LED lights up.
4. Do not use in an environment laden with oil
or chemicals.
Consult with SMC if auto switches will be used in an
environment laden with coolants, cleaning solvents, various oils
or chemicals. If auto switches are used under these conditions
for even a short time, they may be adversely affected by a
deterioration of the insulation, a malfunction due to swelling of
the potting resin, or hardening of the lead wires.
Other
Warning
1. Consult with SMC concerning water resistance, elasticity of lead wires, and usage at
welding sites.
5. Do not use in an environment with temperature
cycles.
Consult with SMC if switches are to be used where there are
temperature cycles other than normal temperature changes, as
they may be adversely affected internally.
6. Do not use in an environment where there is
excessive impact shock.
<Reed switches>
When excessive impact (300m/s² or more) is applied to a reed
switch during operation, the contact point may malfunction and
generate or cut off a signal momentarily (1ms or less). Consult
with SMC regarding the need to use a solid state switch
depending on the environment.
7. Do not use in an area where surges are
generated.
<Solid state switch>
When there are units (such as solenoid type lifters, high
frequency induction furnaces, motors) that generate a large
amount of surge in the area around cylinders with solid state
auto switches, their proximity or pressure may cause
deterioration or damage to the internal circuit elements of the
switches. Avoid and protect against sources of surge
generation and crossed lines.
8. Avoid close contact with accumulated iron
waste or magnetic substances.
When a large accumulated amount of ferrous waste such as
machining chips or welding spatter, or a magnetic substance
(something attracted by a magnet) is brought into close
proximity to an cylinder with auto switches, this may cause the
auto switches to malfunction due to a loss of the magnetic force
inside the cylinder.

Installation and Removal of Snap Rings
Selection
Caution
Caution
1. Use appropriate pliers (C-type snap ring installing
tool) for installation and removal of snap rings.
2. Even when using appropriate pliers (C-type snap ring
installing tool), proceed with caution as there is a
danger of the snap ring flying off the end of the pliers
(tool) and causing bodily injury or damage to nearby
equipment. After installation, make sure that the snap
ring is securely seated into the snap ring groove
before supplying air.
3. Adjust the cushion needle to reduce excessive
kinetic energy from the piston impact at the stroke
end by allowing it to absorb sufficient kinetic
energy during the cushion stroke.
If due to improper adjustment, the piston impacts the stroke
end with excessive kinetic energy (values above those given in
Table 1), an excessive impact will occur and this may cause
damage to equipment.

Caution
1. Operate the cylinder to the stroke end.
When the stroke is restricted by an external stopper or a
clamped work piece, sufficient cushioning and noise reduction
may not be achieved.
2. Strictly observe the limiting ranges for load weight
and maximum speed (Graph 1). Also, the limiting
ranges provided here are based on the condition
that the cylinder is operated to the stroke end with a
proper cushion needle adjustment.
If operated beyond the limiting ranges, excessive impact will
occur and this may cause damage to equipment.

Use a 3mm flat head watchmakers screwdriver to adjust the
cushion needle. The adjustment range for the cushion needle
must be between the fully closed position and the open position
ranges indicated in the above table. A retaining mechanism
prevents the cushion needle from slipping out; however, it may
spring out during operation if it is rotated beyond the ranges
shown above.
