Cautions

● Never use this product as a sensing device for personnel protection.
● In case of using devices for personnel protection, use products which meet laws and
standards, such as OSHA, ANSI or IEC etc., for personnel protection applicable in
each region or country.
● This product has been developed / produced for industrial use only.
● The thin cable 0.1mm
with excessive force, it may cause cable break.
● Extension up to total 50m (emitter and receiver each of thru-beam type) is possible with
2
a 0.3mm , or more of conductor cross-section area 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.
● Make sure to carry out wiring in the power supply OFF condition.
● Take care that wrong wiring will damage the sensor.
● 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 regulator, ensure that the frame ground
(F.G.) terminal of the power supply is connected to an actual ground.
● In case noise generating equipment (switching 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 use during the initial transient time (50ms) after the power supply is switched
ON.
● Make sure to use an isolation transformer for the DC power supply. If an auto-transformer
(single winding transformer) is used, this product or the power supply may get damaged.
● In case a surge is generated from power supply, take countermeasures such as con-
necting a surge absorber to the origin of the surge.
● 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 per-
formance.
● This sensor is suitable for indoor use only.
● Do not use this sensor in places having excessive vapor, dust, etc., or where it may
come in contact with corrosive gas, etc.
● Take care that the product does not come in contact with oil, grease, organic solvents
such as thinner, etc., strong acid or alkaline.
● In case of using the sensor at a place where static electricity is generated, use a metal
mounting plate. Also, ensure to ground the mounting plate.
