Sensing range
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 correspond‐
ing diagram
[see figure
3] (x = sensing range, y = monitored area between the set
sensing range and background suppression as a % of the sensing range (object remis‐
sion/background remission)). Remission: 6% = black 1, 18% = gray 2, 90% = white 3
(referring to standard white as per DIN 5033).
The minimum distance (= y) for background suppression can be determined from
diagram [
see figure 3
1] as follows:
Example: x = 150 mm, y = 20 => 20% of 150 mm = 30 mm. That is, the background is
suppressed at a distance of > 180 mm from the sensor.
