The RP 20 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
- insensitive against ambient light
- high degree of protection
- optional cable entry
- terminal compartment
- polarisation filter optical system
- test input
- protected against power supply polarity reversal
- RP 20 operating voltage 15...36VDC
- relay output
- easy adjustment of the optical sensor
- soiling indication
- LED alignment indication
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.
Potential-free changeover contact
Protected against polarity reversal:
The photo-electric switch is protected against power supply polarity reversal
The RP20 has a large terminal compartment. The screw terminals can also be pulled out for easy connection.
Even when the casing is fixed in position, the photo-electric switch can be adjusted using three adjustment screws on the circuit board.
If the photo-electric switch gradually becomes soiled, the red LED starts to flash before the photo-electric switch becomes ineffective.
The alignment LED flashes red when the photo-electric switch is not optimally aligned to the reflector. Alignment OK = LED lights up green
