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
table 9 . Once the sensing
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 3 and
table 7 ].
