1.2.2 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.
● Note that, if this product is used for many hours, the brightness of the display section drops
over time due to aging.
● If there are objects with high reflectance around the detection point, the product may be
affected by ambient leakage light.
● Specular reflection of light may prevent normal measurement if it enters the beam receiving
part. Be careful when installing the product if the reflectance of the sensing objects is high.
● For high-precision sensing, perform an analog scaling and a span adjustment in the actual
installation conditions.
Power Supply
● Verify that the supply voltage fluctuations are within the rating when using the product.
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.
• The power supply unit must be certified for use in your region.
• The output holding time of the power supply unit must be 20 ms or more.
• The current capacity (recommended current capacity including starting current, external
output current, and analog output current) of the power supply unit must be 500 mA or
more, including a rated output voltage of 24 VDC ±10 % and a ripple of 0.5 V (P-P).
• If CE marking is required, the Safety Extra Low Voltage (SELV) or Protective Extra Low
Voltage (PELV) of the power supply unit must comply with the EMC Directive.
