PRECAUTIONS FOR PROPER USE

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.
Mounting
The tightening torque
should be 0.8 N m or
less.
Care must be taken regarding the sensor mounting direction with
respect to the object's direction of movement.

Sensing object
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.

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 m.

Automatic interference prevention function

When the sensors are mounted closely, use them in the
interference prevented area, as shown below.

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