Photo sensor QS18VP6AF250Q8, background suppression 30-250 mm, PNP, NO/NC, 10-30VDC, M12 4-pin

QS18VP6AF250Q8 is a Banner QS18 series photo sensor with adjustable background suppression and a visible red 640 nm LED beam. Objects up to the set cutoff are detected regardless of colour, while anything beyond it is ignored.

• Sensing range: cutoff adjustable 30-250 mm
• Output: complementary PNP, Light Operate and Dark Operate, 50 mA per output
• Response: 1.7 ms ON, 1.1 ms OFF; repeatability 130 µs
• Supply: 10-30 V DC, < 475 mW
• Housing: ABS, 18 mm threaded nose or side mounting
• Environment: IP67, -40...+60 °C
• Connection: integral M12 4-pin male connector

The cutoff distance is set with a single-turn potentiometer. A crosstalk algorithm lets two sensors work close to each other. A green LED indicator shows power; the amber one shows light sensed and flashes at a marginal condition.
