Inductive Sensors

Wiring

High-tension Lines

Wiring through Metal Conduit

:

If there is a power or high-tension line near the cable of the Proximity
Sensor, wire the cable through an independent metal conduit to pre-
vent against Proximity Sensor damage or malfunctioning.

Cable Extension

The standard cable length is less than 200 m.
The tractive force is 50 N.

Mounting

The Proximity Sensor must not be subjected to excessive shock with
a hammer when it is installed, otherwise the Proximity Sensor may
be damaged or lose its water-resistance.
Do not tighten the nut with excessive force. A washer must be used
with the nut.

Maintenance and Inspection

Periodically perform the following checks to ensure stable operation
of the Proximity Sensor over a long period of time.

1.

Check for mounting position, dislocation, looseness, or distortion
of the Proximity Sensor and sensing objects.

2.

Check for loose wiring and connections, improper contacts, and
line breakage. 

3.

Check for attachment or accumulation of metal powder or dust.

4.

Check for abnormal temperature conditions and other environ-
mental conditions.

5.

Check for proper lighting of indicators (for models with a set indi-
cator).

Never attempt to disassemble or repair the Sensor.

Environment

Water Resistivity

The Proximity Sensors are tested intensively on water resistance, but
to ensure maximum performance and life expectancy, avoid immer-
sion in water and provide protection from rain or snow.

Operating Environment

Store and operate the Proximity Sensor only within the given specifi-
cations.

Inrush Current

A load that has a large inrush current (e.g., a lamp or motor) will
damage the Proximity Sensor. Connect the load to the Proximity
Sensor through a relay.
