Subject to change without notice
range and suppression of the background as a % of the sensing range (object remis‐
sion/background remission). Remission: 6% = black, 18% = gray, 90% = white (refer‐
ring to standard white as per DIN 5033).
The minimum distance (= y) for background suppression can be determined from
diagram [H] as follows:
Example H: Sensing range 115 mm on gray: x = 40 mm, y = 10 => 10 of 40 mm = 4
mm. That is, the background is suppressed at a distance of > 44mm from the sensor.

Mount the sensor using a suitable mounting bracket (see the SICK range of accesso‐
ries).
Observe the maximum permissible tightening torque of the sensor of 2.0 Nm for
metal/0.9 Nm for plastic [K].
