Photo sensor - receiver QS30RRXH2OQ5-83044, water detection, 4 m, PNP/NPN, dark operate, 10-30VDC, M12 5-pin

QS30RRXH2OQ5-83044 is the high-gain dark operate receiver of a Banner QS30H2O opposed-mode water sensor pair, used with a standard QS30EXH2O emitter over up to 4 m. The 1450 nm infrared beam is tuned to an absorption band of water: it passes through many plastic and glass containers but is attenuated by water-based liquids, so the pair sees whether a container is filled.

• Sensing range: 4 m with a QS30EXH2O emitter
• Output: bipolar, one PNP and one NPN, Dark Operate, 100 mA
• Response: 1 ms ON/OFF, repeatability 500 µs at 10x excess gain or more; 3 ms and 2.5 ms at 2-10x
• Supply: 10-30 V DC, < 65 mA
• Housing: PC/ABS, PMMA window, M30x1.5 threaded barrel or side mounting
• Environment: IP67, NEMA 6, 1200 psi washdown per NEMA PW12, -20...+60 °C
• Connection: 150 mm PVC cable with M12 5-pin male connector

The high-gain receiver suits translucent containers and thick liquid layers, such as HDPE milk containers or coloured PET bottles. The output is on while the beam is blocked. Works with a standard QS30EXH2O emitter, ordered separately. Modulation frequency A or B is chosen with the grey wire and must match on emitter and receiver, so neighbouring pairs do not interfere.
