OR18.RR-PW1P.71O is a Baumer M18 retro-reflective photo sensor with a polarisation filter and a 3.5 m operating range. The polarisation filter lets the sensor tell the reflector from shiny objects, so glossy packaging or metal parts do not hold the output switched. Sensitivity is set with a 270° potentiometer on the housing.
- Operating range: 3.5 m (nominal 4.5 m), red LED 660 nm
- Output: PNP, max. 100 mA, light/dark operate; response time < 1 ms
- Supply: 12...30 V DC, max. 40 mA
- Housing: M18 x 1 threaded, 67.2 mm long, ABS plastic, PMMA lens
- Environment: IP67; -25...+55 °C
- Connection: M12 4-pin connector
Used for object detection across conveyors and gates where a reflector can be mounted opposite the sensor. Pin 2 (white) is a control input. A green LED shows alignment and lens soiling, a yellow LED shows the output state.
