Precautions for Correct Use
Check the relation between the sensing object
and the Proximity Sensor.
Verify the electrical conditions of the control system
to be used and the electrical performance of the
Proximity Sensor.

The environmental tolerance of the Proximity Sensor
is better than that of other types of Sensors. However,
investigate carefully before using a Proximity Sensor
under harsh temperatures or in special atmospheres.

Mounting procedure
Installation location
Do not use the Sensor in water, rain, or outdoors.
To maintain reliability of operation, do not use the
Sensor outside the specified temperature range or
outdoors. Even though the Proximity Sensor has a
water-resistant structure, it must be covered to pre-
vent direct contact with water or water-soluble cutting
oil. Do not use the Sensor in atmospheres with chem-
ical vapors, in particular, strong alkalis or acids (nitric
acid, chromic acid, or hot concentrated sulfuric acid).
Do not use the Sensor in atmospheres where
there is a danger of explosion. Use an Explosion-
proof Sensor.
