Safety Precautions
Refer to Warranty and Limitations of Liability on page 20.
This product is not designed or rated for ensuring
safety of persons. Do not use it for such purpose.
The following precautions must be observed to ensure safe oper-
ation 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 de-
gree of protection will not be maintained and the Sensor may be-
come loose due to vibration. The appropriate tightening torque is
0.3 to 0.4 N·m.
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.
Oily Environments
Do not use the Sensor in oily environments.
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.
Washing
Do not use highly concentrated detergents. They may cause mal-
function. Do not use high-pressure water spray in excess of the
specifications.
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.

Caution
Precautions for Safe Use
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 supply.
Otherwise, explosion may result.
When cleaning the product, do not apply a
concentrated spray of water to one location.
Otherwise, parts may become damaged and the
degree of protection may be degraded.
High-temperature environments may result in burn
injury.
