Photoelectric Sensors Technical Guide
Precautions for Correct Use
● Design
Power Reset Time
Turning OFF Power
The Sensor will be ready to detect within approximately 100 ms after
the power is turned ON.
If the Sensor and the load are connected to separate power supplies,
turn ON the Sensor power before turning ON the load power. Any
exceptions to this rule are indicated in Safety Precautions in individual
product information.
An output pulse may be generated when the power is turned OFF. It
is recommended that the load or load line power be turned OFF
before the Sensor power is turned OFF.
Power Supply Types
An unsmoothed full-wave or half-wave rectifying power supply cannot
be used.
Mutual Interference
Mutual interference is a state where an output is unstable because the Sensors are affected by light from the adjacent Sensors.
The following measures can be taken to avoid mutual interference.
Countermeasure
1

Concept
Through-beam Sensors
Reflective Sensors
Use a Sensor
with the
interference
prevention
function.
If Sensors are mounted in close proximity, use Sensors with the interference prevention function.
10 or fewer Sensors: E3X-DA@-S, E3X-MDA, E3C-LDA Fiber Sensors
Performance, however, will depend on conditions. Refer to pages E3X-DA-S/E3X-MDA
and E3C-LDA.
5 or fewer Sensors: E3X-NA Fiber Sensors
2 or fewer Sensors: E3T, E3Z, E3S-C, E3G-L1/L3, or E3S-C Built-in Amplifier Photoelectric Sensors (except
Through-beam Sensors)
E3C Photoelectric Sensor with separate amplifier
Install an
inference
prevention
filter.
A mutual interference prevention polarizing filter can be
installed on only the E3Z-TA to allow close-proximity
mounting of up to 2 Sensors.
Mutual Interference Prevention Polarizing Filter: E39-E11
Separate
Sensors to
distance where
interference
does not occur.
Check the parallel movement distance range in the
catalog, verify the set distance between adjacent
Sensors, and install the Sensors accordingly at a
distance at least 1.5 times the parallel movement
distance range.
--If the workpieces move from far to near, chattering may
occur in the vicinity of the operating point. For this type of
application, separate the Sensors by at least 1.5 times the
operating range.

Sensor
Close mounting of Sensors is possible by alternating
the Emitters with the Receivers in a zigzag fashion (up
to two Sensors). However, if the workpieces are close
to the Photoelectric Sensors, light from the adjacent
Emitter may be received and cause the Sensor to
change to the incident light state.

If there is a possibility that light from another Sensor
may enter the Receiver, change the position of the
Emitter and Receiver, place a light barrier between the
Sensors, or take other measures to prevent the light
from entering the Receiver.
(Light may enter even if the Sensors are separated by
more than the sensing distance.)
If Sensors are mounted in opposite each other, slant the
Sensors as shown in the following diagram. (This is
because the Sensors may affect each other and cause
output chattering even if separated by more than the
Sensor sensing distance.)

● Wiring
Cable
Separation from High Voltage (Wiring Method)
Unless otherwise indicated, the maximum length of cable extension is
100 m using wire that is 0.3 mm2 or greater.
Exceptions are indicated in Safety Precautions in individual product
information.
Do not lay the cables for the Sensor together with high-voltage lines
or power lines. Placing them in the same conduit or duct may cause
damage or malfunction due to induction interference. As a general
rule, wire the Sensor in a separate system, use an independent metal
conduit, or use shielded cable.

When wiring the cable, do not subject the cable to a tension greater than
that indicated in the following table.
Cable diameter
Less than 4 mm
4 mm or greater
Tensile strength
30 N max.
50 N max.
Note: Do not subject a shielded cable or coaxial cable to tension.
Repeated Bending

● Operating Environment
Water Resistance
● Maintenance and Inspection
Points to Check When the Sensor Does Not Operate
Do not use in water, in rain, or outside.
• If the Sensor does not operate, check the following points.
(1) Are the wiring and connections correct?
(2) Are any of the mounting screws loose?
(3) Are the optical axis and sensitivity adjusted correctly?
(4) Do the sensing object and the workpiece speed satisfy the ratings
and specifications?
(5) Are any foreign objects, such as debris or dust, adhering to the
Emitter lens or Receiver lens?
(6) Is strong light, such as sunlight (e.g., reflected from a wall), shining
on the Receiver?
(7) Do not attempt to disassemble or repair the Sensor under any
circumstances.
Ambient Conditions
Do not use this Sensor in the following locations. Otherwise, it may
malfunction or fail.
(1) Locations exposed to excessive dust and dirt
(2) Locations exposed to direct sunlight
(3) Locations with corrosive gas vapors
(4) Locations where organic solvents may splash onto the Sensor
(5) Locations subject to vibration or shock
(6) Locations where there is a possibility of direct contact with water,
oil, or chemicals
(7) Locations with high humidity and where condensation may result
Lens and Case
Environmentally Resistive Sensors
The E32-T11F/T12F/T14F/T81F-S/D12F/D82F and E3HQ can be used
in locations (3) and (6) above.
Optical Fiber Photoelectric Sensors in Explosive Gas
Atmospheres
The Fiber Unit can be installed in the hazardous area, and the
Amplifier Unit can be installed in a non-hazardous area.
<Reason>
For explosion or fire due to electrical equipment to occur, both the
hazardous atmosphere and a source of ignition must be in the same
location. Optical energy does not act as an ignition source, thus there
is no danger of explosion or fire. The lens, case, and fiber covering are
made of plastic, so this setup cannot be used if there is a possibility of
contact with solvents that will corrode or degrade (e.g., cloud) the
plastic.
● Accessories
Using a Reflector (E39-R3/R37/RS1/RS2/RS3)
During Application
(1) When using adhesive tape on the rear face, apply it after washing
away oil and dust with detergent. The Reflector cannot be
mounted if there is any oil or dirt remaining.
(2) Do not press on the E39-RS1/RS2/RS3 with metal or a
fingernail.This may weaken performance.
(3) This Sensor cannot be used in locations where oil or chemicals
may splash on the Sensor.
M8 and M12 Connectors
<Ignition Source>
Electrical sparks or high-temperature parts that have sufficient energy
to cause explosion in a hazardous atmosphere are called ignition
sources.
Hazardous area
The lens and case of the Photoelectric Sensor are primarily made of
plastic. Dirt should be gently wiped off with a dry cloth. Do not use
thinner or other organic solvents.
• The case of the E3S-C is metal. The lens, however, is plastic.
Non-hazardous area
Fiber Unit
Amplifier Unit
Sensing object
Influence from External Electrical Fields
Do not bring a transceiver near the Photoelectric Sensor or its wiring,
because this may cause incorrect operation.
• Be sure to connect or disconnect the connector after turning OFF
the Sensor.
• Hold the connector cover to connect or disconnect the connector.
• Secure the connector cover by hand. Do not use pliers, otherwise
the connector may be damaged.
• If the connector is not connected securely, the connector may be
disconnected by vibration or the proper degree of protection of the
Sensor may not be maintained.
● Others
Values Given in Typical Examples
The data and values given as typical examples are not ratings and
performance and do not indicate specified performance. They are
rather values from samples taken from production lots, and are
provided for reference as guidelines. Typical examples include the
minimum sensing object, engineering data, step (height) detection
data, and selection list for specifications.
Cleaning
