Photo sensor Q20PD, diffuse 250 mm, PNP, NO/NC, 10-30VDC, 2 m cable

Q20PD is a Banner Q20 series short-range diffuse photo sensor with a visible red 624 nm beam. It detects an object by the light the object reflects back to the sensor, so no reflector or separate receiver is needed.

• Sensing range: 250 mm on a 90 % white test card
• Output: PNP, complementary Light Operate and Dark Operate outputs, 100 mA
• Response: 850 µs ON/OFF; repeatability 90 µs
• Supply: 10-30 V DC, < 18 mA
• Housing: ABS, PMMA lenses
• Environment: IP67, -20...+60 °C
• Connection: 2 m PVC cable, 4 wires

A green LED indicator shows power; the amber one shows the output state and flashes at marginal excess gain. Sensitivity is set with a single-turn potentiometer.

Vibration tested to MIL-STD-202F, method 201A; shock to IEC 60947-5-2.
