The minimum distance (= y) for background suppression can be determined from
diagram [H] as follows:
Example: x = 100 mm, y = 7 => 7 % of 100 mm = 7 mm. That is, the background is
suppressed at a distance of > 107mm from the sensor.

2 Mount the sensor using a suitable mounting bracket (see the SICK range of acces‐
sories).
Note the sensor's maximum permissible tightening torque of 0.8 Nm.

Output oscillates at 2 Hz if an object is located within the sensing range.
4 Align the sensor with the object. Select the position so that the red emitted light
beam hits the center of the object. You must ensure that the optical opening (front
screen) of the sensor is completely clear [E]. We recommend making the adjust‐
ments using an object with a low remission.
