Product Mounting
● When securing the main body with
screws, use M3 screws with tight-
ening torque of 0.5N·m or less.
● Use plain washers of small round
type (ø6mm).
● Please prepare M3 screws and
spring washers, plain washers
separately.

● Be sure to mount the tube in close contact with the sens-
ing element. Otherwise, the product may malfunction. If
the tube is brought up or slips off, take additional mea-
sures such as attaching an auxiliary fitting to fix the tube.
● Please prepare the auxiliary fitting for
fixing the tube separately.

5 CAUTIONS
● This product has been developed / produced for in-
dustrial use only.
● Make sure to carry out wiring in the power supply OFF condition.
● Take care that if a voltage exceeding the rated range
is applied, or if an AC power supply is directly con-
nected, the product may get burnt or damaged.
● Take care that short circuit of the load or wrong wiring
may burn or damage the product.
● 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.
● Verify that the supply voltage variation is within the rating.
● If power is supplied from a commercial switching reg-
ulator, ensure that the frame ground (F.G.) terminal of
the power supply is connected to an actual ground.
● In case noise generating equipment (switching regu-
lator, inverter motor, etc.) is used in the vicinity of the
mounting part of this product, connect the frame ground
(F.G.) terminal of the equipment to an actual ground.
● Do not use during the initial transient time (50ms) af-
ter 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 de-
vice or sunlight etc., as it may affect the sensing performance.
● Extension up to total 100m (each emitter and receiver
of thru-beam type), or less, is possible with 0.3mm
or more of conductor area cable. However, in order to
reduce noise, make the wiring as short as possible.
