Photo sensor Q20-2VNLP-2M, polarized retroreflective 5 m, NPN, LO and DO outputs, 10-30VDC, 2 m cable

Q20-2VNLP-2M is a Banner Q20-2 series polarized retroreflective photo sensor with a visible red 645 nm beam and a 5 m range with a BRT-92X92C reflector. The polarizing filter lets it detect dark and shiny objects.

• Sensing range: 5 m with BRT-92X92C reflector
• Output: two NPN, one Light Operate and one Dark Operate (complementary), 100 mA total
• Response: 600 µs; repeatability 144 µs
• Supply: 10-30 V DC, < 20 mA
• Housing: ABS, acrylic lens, 3 mm mounting holes at 25.4 mm spacing
• Environment: IP67, -25...+70 °C
• Connection: 2 m PVC cable, 4 wires

A green LED indicator shows power; the amber one shows light sensed and flashes at a marginal sensing condition. Sensitivity is set with a single-turn potentiometer.
