RP 20 reflective photo-electric switch

Polarisation filter:
Detects even "shiny" objects between the photo-electric switch and the reflector.

Large maximum range:
Provides capacity to allow for dirt, rain, snow and fog.

Optional cable entry:
Two break-out ports are provided in the casing. Cable entry can be from below or from the rear.

Immune to external light sources:
The photo-electric switch is unaffected by external light sources or sunlight.

High degree of protection:
The hermetically sealed casing is suitable for exterior use.

Relay output:
Potential-free changeover contact

Protected against polarity reversal:
The photo-electric switch is protected against power supply polarity reversal

Terminal compartment:
The RP20 has a large terminal compartment. The screw terminals can also be pulled out for easy connection.

Adjustment screws:
Even when the casing is fixed in position, the photo-electric switch can be adjusted using three adjustment screws on the circuit board.

Soiling indication:
If the photo-electric switch gradually becomes soiled, the red LED starts to flash before the photo-electric switch becomes ineffective.

Alignment indication:
The alignment LED flashes red when the photo-electric switch is not optimally aligned to the reflector. Alignment OK = LED lights up green
