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 (background) and the object 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 reliable object detection can be determined from
diagram [H] as follows:
Example: x = 100 mm, y = -5% => -5%% of 100 mm = -5 mm. That is, the distance
between the object and the background must be at least 95 mm.

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

L = light switching
D = dark switching
Alarm / Health = diagnostics output (see Additional functions)
4 Align the sensor with a fixed background. You must ensure that the optical opening
(front screen) of the sensor is completely clear [see Graphic E/F].
