Sensing range setting
The sensing range is adjusted with the potentiometer (type: Multiturn, 7 rotations).
Clockwise rotation: sensing range increased; counterclockwise rotation: sensing range
reduced. It is recommended to place the object within the sensing range, e.g. see
table 11. Once the sensing range has been adjusted, the object is removed from the
path of the beam, which causes the background to be suppressed. The digital output
changes [see table 6 and table
Adjustable sensing range: 100 mm ... 3000 mm.
