Installation and Adjustment
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 200×200mm of non-glossy white paper. Be sure that
it can be different by size, surface and gloss of target.

Photoelectric
sensor
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
operation 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 Ø8mm, it can be missed by sensor because light
penetrate it.
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 0.8 N.m.
Do not impact on the unit with the hard object or bend the cable with excessive power. Otherwise, It may result in damage
to the waterproof function.

1. Supply the power to the photoelectric sensor, after
setting the photoelectric sensor and the reflector (MS-2)
or reflective tape face to face.
2. Set the photoelectric sensor in the position which
indicator turns on, by adjusting the reflector, reflective
tape 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 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.
※
If the mounting place is too narrow,
please use MS-5 instead of MS-2.
※Please use reflective tape (MST
series) for where a reflector is not
installed.

Reflectivity by Reflective Tape
Model
※This reflectivity is based on the reflector (MS-2).
※Reflectivity may vary depending on usage environment
and installation conditions.
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
min. 20mm.
