Setting Distance Formula
Detecting distance can be changed by
the shape, size or material of the target.
For stable sensing, install the unit within
the 70% of sensing distance.
Setting distance (Sa)
= Sensing distance (Sn) × 70%
Mutual-interference & Influence by Surrounding Metals
■ Mutual-interference
When plural proximity sensors are mounted in a close row, malfunction of sensor may
be caused due to mutual interference.
Therefore, be sure to provide a minimum distance between the two sensors, as below
table.
[Face to Face]

■ Influence by surrounding metals
When sensors are mounted on metallic panel, it must be prevented sensors from being
affected by any metallic object except target. Therefore, be sure to provide a minimum
distance as below chart.

Tightening Torque
Use the provided washer to tighten the nuts.
The tightening torque of the nut varies with the distance from the fore-end. [Figure 1]
If the nut tip is located at the front of the product, apply the front tightening torque.
the allowable tightening torque table is for inserting the washer as [Figure 2].
