Photo sensor SM312WQD, divergent diffuse 130 mm, PNP/NPN, LO/DO, 10-30VDC, M12 4-pin

SM312WQD is a Banner MINI-BEAM divergent diffuse photo sensor with an infrared 880 nm beam and a 130 mm range. The wide beam detects objects by the light they reflect back, without precise aiming at the target.

• Sensing range: 130 mm
• Output: bipolar, one PNP and one NPN, Light or Dark Operate selected by switch, 150 mA each (100 mA at +70 °C)
• Response: 1 ms; repeatability 0.3 ms
• Supply: 10-30 V DC, < 25 mA
• Housing: reinforced thermoplastic polyester, fully encapsulated, o-ring sealed, acrylic lens
• Environment: IP67, -20...+70 °C
• Connection: integral M12 4-pin male connector

Sensitivity is set with a 15-turn potentiometer and the LO/DO switch, both under a gasketed clear cover on the rear panel. The rear AID LED pulses faster as the received signal gets stronger, which helps when setting up.
