Photo sensor - emitter OR18W.TI-ZZZP.9VO, through-beam, 13 m, 12-30VDC, M18 stainless steel, M12 4-pin

OR18W.TI-ZZZP.9VO is the emitter half of the Baumer OR18W through-beam pair, in a washdown stainless steel 1.4404 (V4A) housing rated IP 67/69K. It carries no switching output - it only sends the infrared beam, and the matching OR18W receiver does the detecting.

• 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: 13 m actual (nominal 20 m), pulsed infrared diode 880 nm
• Emission power: adjustable, 270° potentiometer
• Supply: 12...30 V DC, max. 40 mA
• Connection: M12 4-pin connector

Pins 2 and 4 (white and black) are the ON/OFF inputs, so the beam can be switched off from the controller without cutting the supply - useful when two pairs face each other and have to be run alternately. A green LED shows that the emitter is powered. The receiver is ordered separately.
