• Follow instructions in ‘Cautions during Use’. Otherwise, It may cause unexpected
accidents.
• When connecting an inductive load such as DC relay or solenoid valve to the output,
remove surge by using diodes or varistors.
• Use the product after 0.5 sec of the power input.
When using a separate power supply for the sensor and load, supply power to the
sensor 󹃗rst.
• The power supply should be insulated and limited voltage/current or Class 2, SELV
power supply device.
• Wire as short as possible and keep it away from high voltage lines or power lines to
prevent surge and inductive noise.
• When using switching mode power supply (SMPS), ground F.G. terminal and connect
a condenser between 0V and F.G. terminal to remove noise.
• When using a sensor with a noise-generating equipment (e.g., switching regulator,
inverter, and servo motor), ground F.G. terminal of the equipment.
• This unit may be used in the following environments.
- Indoors (in the environment condition rated in ‘Speci󹃗cations’)
- Altitude max. 2,000 m
- Pollution degree 3
- Installation category II

• Be sure to install this product by following the usage environment, location, and speci󹃗ed
ratings. Consider the listed conditions below.
- Installation environment and background (re󹃘ected light)
- Sensing distance and sensing target
- Direction of target’s movement
- Characteristic curves
• When installing multiple sensors closely, it may result in malfunction due to mutual
interference.
• For installation, tighten the screw with a torque of 0.5 N m. Mount the brackets correctly to
prevent the twisting of the sensor’s optical axis.
• Do not impact with a hard object or bend the cable excessively. That could decrease the
product’s water resistance.
• Use this product after the test. Check whether the indicator works appropriately for the
positions of the detectable object.

Sensitivity Adjustment
• Set the adjuster for stable Light ON area, minimizing the e󹃖ect of the installation environment.
• Use the o󹃖ered adjustment screwdriver. Do NOT turn with excessive force to prevent
product damage.
• The steps below are based on Light ON mode.

Turn the adjuster from MIN to MAX sensitivity and
check the position (A) where the operation indicator
activates under the light ON area.
02 Interrupted
Turn the adjuster from (A) to MAX and check the
position (B) where the operation indicator activates
under the light OFF area.
If the operation indicator does NOT activate at the
MAX (maximum sensitivity): MAX = (B).
03 -Set the adjuster at the mid position between (A) and
