Photo sensor Q20PAF200, background suppression 30...200 mm, PNP, NO/NC, 10-30VDC, 2 m cable

Q20PAF200 is a Banner Q20 series photo sensor with adjustable background suppression and a visible red 640 nm beam. Objects up to the set cutoff are detected regardless of colour, while anything beyond it is ignored.

• Sensing range: adjustable cutoff 30...200 mm
• Output: complementary PNP, Light Operate and Dark Operate, 50 mA total
• Response: 1.7 ms ON, 1.1 ms OFF; repeatability 130 µs
• Supply: 10-30 V DC, < 300 mW
• Housing: ABS front, copolyamide rear, PMMA lenses, 3 mm mounting holes at 25.4 mm spacing
• Environment: IP67, -20...+60 °C
• Connection: 2 m PVC cable, 4 wires

The cutoff is set with a single-turn potentiometer. A green LED indicator shows power; the amber one shows light sensed and flashes at a marginal sensing condition. Two sensors can be mounted close together without crosstalk.
