The minimum distance (= y) for background suppression can be determined from diagram
[ figure 6 1] as follows:
Example: x = 600 mm, y = 4.5 => 4.5% of 600 mm = 27 mm. That is, the background is
suppressed at a distance of > mm from the sensor.

3 Sensing range setting
Sensor with potentiometer: open the sensor cover and protective hood, make sure that no
dirt has gotten into the sensor.
The sensing range is adjusted with the potentiometer (type: without stop ). Clockwise rota‐
tion: sensing range increased; counterclockwise rotation: sensing range reduced. We rec‐
ommend placing the object within the sensing range, e.g. see
range has been adjusted, the object is removed from the path of the beam, which causes
the background to be suppressed and the switching output to change [see
table 7].
