Inductive Sensors
Power OFF
The Proximity Sensor may output a pulse signal when it is turned
OFF. Therefore, it is recommended that the load be turned OFF
before turning OFF the Proximity Sensor.
Power Supply Transformer
When using a DC power supply, make sure that the DC power supply
has an insulated transformer. Do not use a DC power supply with an
auto-transformer.
Mutual Interference
When installing two or more Sensors face-to-face or side-by-side,
ensure that the minimum distances given in the following table are
maintained.
(Unit: mm)
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.
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-resistivity.
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 disassemble or repair the Sensor.
Environment
Water Resistivity
The Proximity Sensors are tested intensively on water resistance, but
in order to ensure maximum performance and life expectancy avoid
immersion in water and provide protection from rain or snow.
Operating Environment
Ensure storage and operation of the Proximity Sensor within the
given specifications.
Inrush Current
A load that has a large inrush current (e.g., a lamp or motor) will
damage the Proximity Sensor, in which case connect the load to the
Proximity Sensor through a relay.
