Hints on Correct Use

Warn ing

 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.
