Safety Precautions• Turn off the power to the product before starting installation, removal, wiring, maintenance, or inspection. Failure to turn power off may cause
electrical shock or fire.

Instructions• Since the power reset time is 100ms, start use after 100ms whenpower is turned on.
• If the load and this product are connected to separate power supplies,
be sure to turn on the power to this product first.
• Do not install or use the product in the following places as it may
cause malfunction or damage.
1) Near induction equipment or heat sources
2) Locations subject to high vibration or shock3) Dusty places
4) Locations subject to harmful gases
5) Locations directly exposed to water, oil, chemicals, etc.
6) Locations where icing may occur• Install the sensor so that light from sunlight or fluorescent lamps does
not directly reach the sensing surface.
• Mirror surfaces with high reflectivity and reflectors may cause
extremely long sensing distances at unexpected sensing ranges.
• Water droplets, dirt, etc., on the sensor surface may affect thesensing performance, so wipe off with a soft cloth before use.
• Since PMMA is used as the material for the optical part,
do not use organic solvents such as ammonia, sodium hydroxide,
alcohol, or thinner.

WiringCautionConnection diagram• Turn off the power to the product before starting wiring.
• Wiring errors may cause damage to the internal circuit. Be sure torefer to the connection diagram.
• Use within the range of the rated operating voltage.
• When using a switching power supply for power, be sure to groundthe FG terminal.
• Avoid parallel wiring using piping or ducts with high-voltage lines
or power lines (especially inverter power lines), as malfunction ordamage may be caused due to inductive noise.
• When long wiring is used or when power sources or electromagnetic
equipment may affect the product, use individual wiring.
• The illumination unit may light dimly due to inductive noise, etc.
In this case, take countermeasures by connecting each terminals
LIGHT1, LIGHT2, and PNP illumination control type to 0V, and byconnecting the below shunt resistor between +V for NPN illumination
control type. (See diagram below)

Shunt resistor R
Resistance value
20kΩ• Do not use a power supply outside the rated operating voltage range
or AC power. Otherwise explosion or burning may occur.
• Avoid continuous lighting of two LED illumination colors
simultaneously, as it may cause damage to the product.
