Safety Precautions

Refer to 

Warranty and Limitations of Liability

 on page 20.

This product is not designed or rated for direct-

ly or indirectly ensuring safety of persons. Do 

not use it for such a purpose.

Do not use the product with voltage in excess 

of the rated voltage. Excess voltage may result 

in malfunction or fire.

Never use the product with an AC power sup-

ply. Otherwise, explosion may result.

When cleaning the product, do not apply a 

high-pressure spray of water to one part of the 

product. Otherwise, parts may become dam-

aged and the degree of protection may be degraded.

High-temperature environments may result in 

burn injury.

The following precautions must be observed to ensure safe operation 
of the Sensor.

Operating Environment

Do not use the Sensor in an environment where explosive or 
flammable gas is present.

Connecting Connectors

Be sure to hold the connector cover when inserting or removing the 
connector. Be sure to tighten the connector lock by hand; do not use 
pliers or other tools. If the tightening is insufficient, the degree of 
protection will not be maintained and the Sensor may become loose 
due to vibration. The appropriate tightening torque is 0.39 to 0.49 N·m 
for M12 metal connectors and 0.3 to 0.4 N·m for M8 metal connectors.

Load

Do not use a load that exceeds the rated load.

Low-temperature Environments

Do not touch the metal surface with your bare hands when the 
temperature is low. Touching the surface may result in a cold burn.

Rotation Torque for Sensitivity Adjustment and Selector 

Switch

Adjust with a torque of 0.06 N·m or less.

Environments with Cleaners and Disinfectants (e.g., 

Food Processing Lines)

Do not use the Sensor in environments subject to cleaners and 
disifectants. They may reduce the degree of protection. 

Modifications

Do not attempt to disassemble, repair, or modify the Sensor.

Outdoor Use

Do not use the Sensor in locations subject to direct sunlight.

Cleaning

Do not use thinner, alcohol, or other organic solvents. Otherwise, the 

optical properties and degree of protection may be degraded.

Surface Temperature

Burn injury may occur. The Sensor surface temperature rises 
depending on application conditions, such as the ambient 
temperature and the power supply voltage. Use caution when 
operating or performing maintenance on the Sensor.

Do not use the Sensor in any atmosphere or environment that 
exceeds the ratings. 

Do not install the Sensor in the following locations.

(1) Locations subject to direct sunlight
(2) Locations subject to condensation due to high humidity
(3) Locations subject to corrosive gas
(4) Locations where the Sensor may receive direct vibration or shock

Connecting and Mounting

(1) The maximum power supply voltage is 30 VDC. Before turning 

the power ON, make sure that the power supply voltage does not 
exceed the maximum voltage.

(2) Laying Sensor wiring in the same conduit or duct as high-voltage 

wires or power lines may result in malfunction or damage due to 
induction. As a general rule, wire the Sensor in a separate conduit 
or use shielded cable.

(3) Use an extension cable with a minimum thickness of 0.3 mm

2

 and 

less than 100 m long.

(4) Do not pull on the cable with excessive force.
(5) Pounding the Photoelectric Sensor with a hammer or other tool 

during mounting will impair water resistance. Also, use M3 
screws.

(6) Mount the Sensor either using the bracket (sold separately) or on 

a flat surface.

(7) Be sure to turn OFF the power supply before inserting or 

removing the connector.

Cleaning

Never use thinner or other solvents. Otherwise, the Sensor surface 
may be dissolved.

Power Supply

If a commercial switching regulator is used, ground the FG (frame 
ground) terminal.

Power Supply Reset Time

The Sensor will be able to detect objects 100 ms after the power 
supply is tuned ON. Start using the Sensor 100 ms or more after 
turning ON the power supply. If the load and the Sensor are 
connected to separate power supplies, be sure to turn ON the Sensor 
first.

Turning OFF the Power Supply

Output pulses may be generated even when the power supply is OFF. 
Therefore, it is recommended to first turn OFF the power supply for 
the load or the load line.

Load Short-circuit Protection

This Sensor is equipped with load short-circuit protection, but be sure 
to not short circuit the load. Be sure to not use an output current flow 
that exceeds the rated current. If a load short circuit occurs, the output 
will turn OFF, so check the wiring before turning ON the power supply 
again. The short-circuit protection circuit will be reset. The load short-
circuit protection will operate when the current flow reaches 1.8 times 
the rated load current. When using a capacitive load, use an inrush 
current of 1.8 times the rated load current or lower.

Water Resistance

Do not use the Sensor in water, rainfall, or outdoors.
