Degree of contamination in the sensor environment
**----- End of picture text -----**
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. ## Recommended accessories ||**Brief description**|**Type**|**Part no.**| |---|---|---|---| |Universal bar clamp systems|||| ||Plate N12 for universal clamp.
