Cautions during Installation
-
Install the product according to the rated specifications, environment, and place.
-
Tighten the M5 screw with the tightening torque of 0.8 N.m.
-
Installing more than 2 switches closely may result in malfunction due to mutual interference.
Keep the distance between units.
-
Install the switch to the position where the center of the switch and the target be exactly horizontal and vertical.
-
If it is hard to align along the center line, install the switch to the position where the target is closer to the switch part, rather than magnet part.
Otherwise, the target can be attached to the magnet part, so that it can result in malfunction. -
Install the switch to the position where the target passes the sensing point area.
Sensing point area: area between 30 mm point and 40 mm point from the end of the switch
