Interference
prevented area

This product is not a safety sensor. Its use is not
intended or designed to protect life and prevent body
injury or property damage from dangerous parts of
machinery. It is a normal object detection sensor.

• The tightening torque

should be 0.8 N

⅐m or

less.

• Care must be taken regarding the sensor mounting direction with

respect to the object’s direction of movement.

When detecting a specular object (aluminum or copper foil, etc.)
or an object having a glossy surface or coating, please note that
there are cases when the object may not be detected due to a
change in angle, wrinkles on the object surface, etc.
If a specular body is present in the background, faulty operation
may be caused due to a small change in the angle of the
background body. In that case, install the sensor at an inclination
and confirm the operation with the actual sensing object.

• When a specular body is present below the sensor, use the

sensor by tilting it slightly upwards to avoid faulty operation.

This product is not easily affected by the reflected light intensity
since this sensor is the adjustable range reflective type. When
the reflected light intensity is remarkably low, the sensing range
may be affected. In that case, mount the sensor, while checking
light-up of the stable indicator (green).
The mounting screws of the terminal cover and display cover
should certainly be tightened to maintain water-resistance; the
tightening torque of the screws should be 0.3 to 0.5 N

⅐m.

Automatic interference prevention function

• When the sensors are mounted closely, use them in the

interference prevented area, as shown below.

• Note that the detection may be unstable depending on the

mounting conditions or the sensing object to be used.
In the state that this product is mounted, be sure to check the
operation with the actual sensing object to be used.
