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 Sensing object
Do not make the sensor
detect an object in this
direction because it may
cause unstable operation.
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 conrm 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 reected light
intensity since this sensor is the adjustable range reective
type. When the reected 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.

• Never use this product as a sensing device
for personnel protection.
• In case of using sensing devices for
personnel protection, use products which
meet laws and standards, such as OSHA,
ANSI or IEC etc., for personnel protection
applicable in each region or country.
