„ Clamping torque
• Be sure to use the supplied toothed lock
washer when mounting the sensor.
• Do not tighten the sensor’s mounting
screw with a clamping torque higher than
the following values.
„ Wiring
• Separate the wirings of the sensor cable
from power lines and high-tension lines;
Otherwise, the sensor may be caused to
malfunction by noise.
• To extend the wiring, use a cable whose
diameter is almost the same as that of
the sensor cord.
„ Mutual interference
To install plural proximity sensors of the
same model face to face or side by side,
provide the minimum distance indicated in
this table between the sensors.
