Mounting and sensitivity adjustment
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 adjusting the receiver or the
emitter right and left, up and down.
3. After adjustment, check the stability of operation putting
the object at the optical axis.
※
If the sensing target is translucent body or smaller
than ø16mm, it can be missed by sensor cause light
penetrate it.
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 adjustment VR until position
ⓐ
where the
operation indicator turns ON from min. position of the
adjustment VR.
3. Take the target out of the sensing area, then turn the
adjustment VR until position
ⓑ
where the the operation
indicator turns ON. If the indicator dose not turn ON,
max. position is
ⓑ
.
4. Set the adjustment VR at the center of two switching

※
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.
1. Supply the power to the photoelectric sensor, after
setting the photoelectric sensor and the reflector(MS-2)
in face to face.
2. Set the photoelectric sensor in the position which
indicator turns on, as adjusting the reflector or the
sensor right and left, up and down.
3. Fix both units tightly after checking that the unit detects
the target.
※
If using more than 2 photoelectric sensors in parallel,
the space between 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.

Emitter
The light passed through the polarizing filter of the emitter
reaches to the MS-2 reflector converting as horizontal
direction. It reaches to the receiver element of polarizing
filter converting as vertical by the MS-2 reflector. Therefore,
this type can also detect reflective mirror.
Retroreflective type with polarizing filter
※
If the mounting place is too narrow,
please use MS-4 instead of MS-2.
