Handling precautions
Specifications
● This product has been developed and manufactured for industrial use only.
● Do not use this product outside the scope of the specifications. Doing so may result in
accidents or failures.
It will also significantly shorten the service life.
● There is a certain deviation in the directivity of this product. When using this product, install
the product using a mounting bracket or similar fitting to allow the adjustment of beam axis.
● The internal memory (non-volatile memory) of this product has a service life. Settings
cannot be configured more than one million times.
● Due to leak light around the detection point, the measurement values may be affected if
there exist objects with high reflectance around the detecting point.
● If specular reflection light enters the beam receiving part, proper measurement may not be
possible. When the reflectance of a detection object is high, be careful in installation.
● Do not perform wiring or maintenance with wet hands. Doing so may cause an electric
shock.
Power supply
● Verify that the supply voltage fluctuations are within the rating when using the product. Note
that applying a voltage greater than the rated voltage or directly applying AC power will
result in damage or burning.
● To ensure performance, use the product at least 30 minutes (warm-up time) after the power
is turned ON.
● 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.
● Make sure that the power supply input satisfies the following items.
1. The power supply unit must be certified for use in your region
2. The output holding time of the power supply unit must be 20 ms or more
3. The power supply unit must have the rated output voltage of 24 VDC ± 10 % and the
ripple (P/P) of 0.5 V or less, and current capacity of 0.5 A or more.
4. The power supply unit with SELV (Safety Extra Low Voltage) or PELV (Protective Extra
Low Voltage) that comply with the EMC Directive must be used (if the CE marking
compliance is required).
