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 dia‐
gram [H] (x = sensing range, y = minimum distance between the object and background in
mm (object remission/background remission) (remission: 6% = black, 90% = white (based
on standard white DIN 5033))).
The minimum distance (= y) for background suppression can be read from diagram [H
