Photo sensor Q20-2NLP-Q, polarized retroreflective 5 m, NPN, LO/DO, 10-30VDC, M8 4-pin 150 mm cable

Q20-2NLP-Q 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: NPN, Light or Dark Operate selected by switch, 100 mA
• 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: 150 mm PVC cable with M8 4-pin male connector (3-wire sensor)

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. Default mode is Dark Operate.
