PK 1 CENCE retro-reflective sensor =
x Sensing range (m) ASS
At a sensing range of „x“ the photoelectric retro-reflective and through-beam photoelectric
sensors have different operating reserves (see blue arrow). The higher the operating reserve
factor, the better the sensor can compensate the contamination in the air or in the light beam
and on the optical surfaces (front screen, reflector), i.e. the sensor has the maximum availablity,
otherwise the sensor switches due to pollution although there is no object in the path of
the light beam.
Higher operating reserve factor = higher availability
Degree of contamination in the sensor environment
