Photo sensor OR18W.RR-PW1P.9VO, retro-reflective, 3.5 m, PNP, 12-30VDC, M18 stainless steel, M12 4-pin

OR18W.RR-PW1P.9VO is the washdown version of the Baumer OR18 M18 retro-reflective photo sensor: the same 3.5 m range and polarisation filter in a stainless steel 1.4404 (V4A) housing rated IP 67/69K instead of the plastic one.

• Housing: stainless steel 1.4404 (V4A), M18 x 1 thread, 67.2 mm long, PMMA lens
• Environment: IP 67/69K; -25...+55 °C
• Operating range: 3.5 m actual (nominal 4.5 m), pulsed red LED 660 nm, polarisation filter
• Output: PNP, < 100 mA, light/dark operate; response time < 1 ms
• Supply: 12...30 V DC, max. 40 mA
• Connection: M12 4-pin connector

Suited to food, beverage and packaging lines that are washed down at high pressure, where a plastic sensor body would not survive the cleaning cycle. Sensitivity is set with a 270° potentiometer and pin 2 (white) is a control input. A green LED shows alignment against the reflector and lens soiling, a yellow LED the output state.
