Q20-2NLP-Q5 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 M12 4-pin male connector
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.
