1 Check the application conditions: Adjust the sensing range and distance to the
object or background and the remission capability of the object according to the
corresponding diagram [H] (x = sensing range, y = transition range between the set
sensing range and suppression of the background as a % of the sensing range
(object remission / background remission). Remission: 6% = black , 18% = grey
, 90% = white  (referring to standard white as per DIN 5033).
The minimum distance (= y) for background suppression can be determined from
diagram [H] as follows:
Example: x = 100 mm, y = 10% => 10% % of 100 mm = 10 mm. That is, the back‐
ground is suppressed at a distance of > 110mm 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 0.56 Nm.
Note the preferred direction of the object relative to the sensor [see A].
3 The sensors must be connected in a voltage-free state (U
in the graphics [B] must be observed, depending on the connection type:
– Male connector connection: pin assignment
– Cable: core color
