This product has been developed / produced
for industrial use only.
Make sure that the power is off while wiring.
Take care that wrong wiring will damage the
sensor.
Verify that the supply voltage variation is
within the rating.
If power is supplied from a commercial
switching regulator, ensure that the frame
ground (F.G.) terminal of the power supply is
connected to an actual ground.
In case noise generating equipment (switch-
ing regulator, inverter motor, etc.) is used in
the vicinity of this product, connect the frame
ground (F.G.) terminal of the equipment to an
actual ground.
Do not run the wires together with high-volt-
age lines or power lines or put them in the
same raceway. This can cause malfunction
due to induction.
Do not use during the initial transient time
(20ms) after the power supply is switched on.
Take care that the sensor is not directly exposed
to fluorescent lamp from a rapid-starter lamp, a
high frequency lighting device or sunlight etc., as
it may affect the sensing performance.
Extension up to total 100m, or less, is possi-
ble with 0.3mm
2
, or more, cable. However, in
order to reduce noise, make the wiring as
short as possible.
Make sure that stress by forcible bend or pulling
is not applied directly to the sensor cable joint.
This sensor is suitable for indoor use only.
Do not use this sensor in places having exces-
sive vapor, dust, etc., or where it may come in
direct contact with water, or corrosive gas.
Take care that the sensor does not come in
contact with water, oil, grease, organic sol-
vents, such as, thinner etc., or strong acid,
and alkaline.

Beam alignment
Placing the emitter and the receiver face to face
along a straight line, move the emitter in the up,
down, left and right directions, in order to deter-
mine the range of the light received condition
with the help of the operation indicator (red).
Then, set the emitter at the center of this range.
Similarly, adjust for up, down, left and right an-
gular movement of the emitter.
Further, perform the angular adjustment for the
receiver also.

Sensitivity adjustment
Ԙ
ԙ
Ԛ
ԛ
Turn the sensitivity adjuster fully counter-
clockwise to the minimum sensitivity posi-
tion, MIN.
Place an object at the required distance
from the sensor, turn the sensitivity adjust-
er gradually clockwise, and find out point
where the sensor changes to the light re-
ceived condition.
The position at the middle of points and
is the optimum sensing position.
Step Sensitivity adjuster
Description
Remove the object, turn the sensitivity adjuster
further clockwise, and find out point where
the sensor changes to the light received
condition again with only the background.
When the sensor does not go to the light
received condition even if the adjuster is fully
turned clockwise, point is this extreme point.
Optimum position
Note: Use the accessory adjuster screwdriver to turn the distance
adjuster slowly. Turning with excessive force will cause dam-
age the adjuster.
