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.

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.
Note the preferred direction of the object relative to the sensor [see A].

The sensors must be connected in a voltage-free state (V
in the graphics [B] must be observed, depending on the type of connection:
–
Male connector connection: pin assignment
–
Cable: core color
