Photo sensor Q20NDLQ7, diffuse 800 mm, NPN, NO/NC, 10-30VDC, M8 4-pin

Q20NDLQ7 is a Banner Q20 series long-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: 800 mm on a 90 % white test card
• Output: NPN, 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: integral M8 4-pin male connector

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.
