Photo sensor SME312LPQD, polarized retroreflective 3 m, PNP + NPN, 10-30VDC, M12 5-pin

SME312LPQD is a Banner MINI-BEAM Expert polarized retroreflective photo sensor with a visible red 650 nm beam and a range of 10 mm to 3 m. The polarizing filter rejects reflections from shiny objects, so only light returned by the reflector is seen.

• Sensing: polarized retroreflective, 10 mm...3 m with reflector, red 650 nm
• Outputs: bipolar, 1x PNP and 1x NPN, 150 mA each (100 mA at 70 °C); response 500 µs, repeatability 100 µs
• Supply: 10-30VDC, below 45 mA
• Housing: MINI-BEAM, reinforced thermoplastic polyester, encapsulated, M18x1 nose thread with nut
• Environment: IP67, -20...+70 °C
• Connection: integral M12 5-pin connector

Set with the push button or the gray remote TEACH wire: the first condition taught becomes Output ON, so Light or Dark Operate is not selected separately. The green indicator flashes when the signal approaches the switching threshold.
