Safety precautions
This product is not designed or rated for directly 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 malfunc-
tion or fire.
Never use the product with an AC power supply.
Otherwise, explostion may result.
When cleaning the product, do not apply a high-pres-
sure spray of water to one part of the product. Other-
wise, parts may become damaged 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 connectors.
Load
Do not use a load that exceeds the rated load.
Rotation Torque for Sensitivity Adjustment
Adjust with a torque of 0.05 N·m or less.
Environements 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 de-
pending on application conditions, such as the surrounding tem-
perature and the power supply voltage. Use caution when
operating or washing the Sensor.

Precautions for Safe Use
! Warning
! Caution
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
Connecting and Mounting
(1) The maximum power supply voltage is 30 VDC. Before turning
(2) Laying Sensor wiring in the same conduit or duct as high-volt-
(3) Use an extension cable with a minimum thickness of 0.3 mm
(4) Do not pull on the cable with excessive force.
(5) Pounding the Photoelectric Sensor with a hammer or other
(6)Mount the Sensor using a bracket (sold separately).
(7) Be sure to turn OFF the power supply before inserting or re-
Cleaning
Never use thinner or other solvents. Otherwise, the Sensor sur-
face 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 con-
nected 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 cur-
rent flow that exceeds the rated current. If a load short circuit oc-
curs, the output will turn OFF, so check the wiring before turning
ON the power supply again. The short-circuit protection circuit will
be reset.
Water Resistance
Do not use the Sensor in water, rainfall, or outdoors.
