RP20 and RP25 reflective photoelectric switch

RP20 or RP25 reflective photo-electric switch

The RP20/RP25 reflective photo-electric switch has been specially developed for door installations and offers
the optimum solution for this application.

  • reflective photoelectric switch with polarisation filter
  • range 0.5...15m, depending on the type of reflector
  • immune to external light sources
  • high degree of protection
  • optional cable entry
  • terminal compartment
  • polarisation filter optical system
  • test input
  • protected against power supply polarity reversal
  • RP20 operating voltage 15...36VDC
  • RP25 operating voltage 10...40VDC or 24VAC ±25%
  • relay output
  • easy adjustment of the optical sensor
  • soiling indication
  • LED alignment indication

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
