Photo sensor - receiver Q25S2P6RQ, 20 m, PNP with alarm output, 10-30VDC, M12 4-pin

Q25S2P6RQ is the receiver of a Banner EZ-BEAM Q25 series opposed-mode photo sensor pair, in the S2 version for sensor bus junctions. Besides the sensing output it has a second PNP output that warns when the received signal becomes marginal.

• Sensing range: 20 m with a Q256EQ emitter
• Output: PNP Light Operate sensing output and PNP NO alarm output, 150 mA total
• Response: 3 ms ON, 1.5 ms OFF; repeatability 375 µs
• Supply: 10-30 V DC, 20 mA
• Housing: PBT polyester, polycarbonate lens, epoxy-encapsulated electronics
• Environment: IP67, NEMA 6P, -40...+70 °C
• Connection: integral M12 4-pin male connector

The alarm output (white wire) conducts when excess gain falls to 1-1.5x in the light condition, so the bus system sees a dirty lens or misalignment before the sensor stops switching. Using it needs a junction with two channels per input. No adjustments are needed. Works with a Q256EQ emitter, ordered separately.

Vibration tested to MIL-STD-202F, method 201A; shock to method 213B.
