Polarized retro-reflective photoelectric sensor
PRK 72/4 S
–Slim construction with glass lens and robust
metal housing for protection against envi-
ronmental influences
–LEDs as switching state indicators
– Output is short-circuit proof and polarity
reversal protected, thus guaranteeing risk-
less commissioning
– Mounting holes and M4 threads for fast front
side mounting
–Connection via M12 connector, plug or
cable.
