The sensing range gives the mounting distance between the
emitter and the receiver. An object can be detected even if it is
0.17m, or less, away.
Although this product can detect slim objects by using the
cross-beam scanning system, the size of the slim object which
can be stably detected differs with the setting distance. When
this sensor is used to detect slim objects, make sure to confirm
stable detection using the actual objects.

Make sure that the power supply is off while wiring or the
operation of the operation mode switch.
Take care that wrong wiring may 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 e uipment (switching regulator, inverter
motor, etc.) is used in the vicinity of this product, connect the
frame ground (F.G.) terminal of the e uipment to an actual
ground.
Do not run the wires together with high-voltage lines or power
lines or put them in the same raceway. This can cause
malfunction due to induction.
Extension up to total 100m is possible, for both emitter and
receiver, with 0.3mm2, or more, cable. However, in order to
reduce noise, make the wiring as short as possible.
Do not use during the initial transient time (0.5 sec.) after the
power supply is switched on.
Avoid dust, dirt, and steam.
Take care that the sensor does not come in direct contact with
water, oil, grease, or organic solvents, such as, thinner, etc.
Take care that the sensor is not directly exposed to fluorescent
light from a rapid-starter lamp or a high fre uency lighting device,
as it may affect the sensing performance.
The emitter and the receiver must face each other with their cable
ends on the same side. If they are set upside down, the sensor
will not work correctly.
This sensor is suitable for indoor use only.
Although this product can detect slim objects by using the cross-
beam scanning system, the size of the slim object which can be
stably detected differs with the setting distance. Hence, when the
product is used to detect slim objects, make sure to confirm stable
detection using the actual objects.
In case of this sensor, light from the emitter spreads above and
below the sensor. Hence, take care that if there is a reflective
object above or below the product it will affect the sensing.

Place the emitter and the receiver
face to face along a straight line.
After the cables have been correct-
ly connected, switch the power ON.
Move the emitter in the up,
down, left and right directions,
in order to determine the range
of the beam received condition
with the help of the operation indicator (orange) on the receiver.
Then, set the emitter at the center of this range.
Similarly, adjust for up, down, left and right angular movement of
the emitter.
Further, perform the angular adjustment for the receiver also.
Interrupt each beam channel with the actual sensing object, and
confirm that the sensor operates correctly.

٨The output operation mode is selected by the operation mode
switch on the receiver.
The switches must be set with the power supply off. The operation mode
does not change if the switch setting is changed with the power supplied.
