● Design
Influence of Surrounding Metal
When mounting the Sensor within a metal panel, ensure that the
clearances given in the following table are maintained. Failure to
maintain these distances may cause deterioration in the performance
of the Sensor.

Aluminum and Iron Cuttings
Normally aluminum or iron cuttings will not be detected even if they
adhere to or accumulate on the sensing surface.
Detection signals may be output for the following:
If this occurs, remove the cuttings from the sensing surface.

● Mounting
Do not tighten the nut with excessive force.
A washer must be used with the nut.
Part B Part A
Note: 1. The allowable tightening strength depends on the distance from the
edge of the head, as shown in the following table. (A is the distance
from the edge of the head. B includes the nut on the head side. If the
edge of the nut is in part A, the tightening torque for part A applies
instead.)
2. The following torque assume washers are being used.
