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 1.2N.m.
Through-beam type
1. Supply the power to the photoelectric sensor, after
setting the emitter and the receiver facing each other.
2. Set the receiver in center of position in the middle of the
stability range of indicator by adjusting the receiver or
the emitter right and left, up and down.
3. After the adjustment, check the stability of operation by
putting the object at the optical axis.
※If the sensing target is translucent body or smaller than
Ø16mm, it can be missed by sensor because light
penetrate it.

Diffuse reflective type
1. The sensitivity should be adjusted depending on a
sensing target or mounting place.
2. Set the target at a position to be detected by the beam,
then turn the sensitivity adjuster until position ⓐ where
the operation indicator turns ON from min. position of the
sensitivity adjuster.
3. Take the target out of the sensing area, then turn the
sensitivity adjuster until position ⓑ where the operation
indicator turns ON. If the indicator dose not turn ON,
max. position is ⓑ.
4. Set the sensitivity adjuster at the center of two switching
position ⓐ, ⓑ.
※The sensing distance indicated on specification chart is
for 100×100mm of non-glossy white paper. Be sure that
it can be different by size, surface and gloss of target.

※If using more than 2 photoelectric sensors in parallel,
the space among them should be more than 30cm.
※If reflectance of target is higher than non-glossy white
paper, it might cause malfunction by reflection from
the target when the target is near to photoelectric sensor.
Therefore put enough space between the target and the
photoelectric sensor or the surface of the target should
be installed at angle of 30° to 45° against optical axis.
(When a sensing target with high reflectance near by,
photoelectric sensing with the polarizing filter should be
used.)
※Sensitivity adjustment: Refer to the diffuse reflective type’s.

Retroreflective type with polarizing filter
The light passed through the polarizing filter of the emitter
reaches to the MS-2 reflector or reflective tape converting
as horizontal direction. It reaches to the receiver element of
polarizing filter converting as vertical by the MS-2 reflector
or reflective tape. Therefore, this type can also detect
reflective mirror.

※Reflectivity may vary depending on usage environment

The sensing distance and minimum sensing target size
increase as the size of the tape increases.
Please check the reflectivity before using reflective
tapes.
※For using reflective tape, installation distance should be
