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	M5 nut
	M5 (length 30 mm 1.181 in)
• The tightening torque	screw with washers
should be 0.8 N  m or
less.

	(Optional)

•Care must be taken regarding the sensor mounting direction with respect to the object’s direction of movement.

<Correct> <Correct> <Incorrect>

•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  m.

		Do not make the sensor
	Sensing object	detect an object in this
		direction because it may

•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.

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.
