Installation and Adjustment
For mounting
Notice for BGS reflective type
When using photoelectric sensors closely over two units,
it may result in malfunction due to mutual interference.
When installing the product, tighten the screw with a
tightening torque of 0.3N.m.
※Do not impact on the unit with hard objects and do not
bend the cable part too much. It may cause damage to
waterproof function.

● Diffuse reflective/BGS reflective type
1) Make sure that the sensing side
of this sensor is parallel with the
surface of each sensing object.
2) If the sensing object has glossary
surface or high reflection, the
sensor tilts from 5 to 10˚as
shown in the figure.
Make sure whether the sensor is
influenced by any background
objects.

Set the emitter and the receiver facing each other and adjust
these up·down, right·left after checking the point of operating
the stability indicator. Fix the emitter and the receiver at the
center of the point.

● Diffuse reflective/BGS reflective type
After placing a sensing target, fix it in the middle of position
where the stability indicator operates when adjusting the
sensor to up·down, right·left. Make sure that the sensing
side of the sensor is parallel with the surface of each sensing
target.
