Banner Engineering QS18VN6LPQ5 Photoelectric Sensor

QS18VN6LPQ5 from Banner Engineering is an 18 mm QS18 World‑Beam photoelectric sensor with a polarized retroreflective sensing mode and an NPN discrete output. It operates on 10–30 V DC, uses a visible red LED beam, and arrives in a rugged ABS rectangular housing with M18 mounting rated IP67/NEMA 4X for demanding industrial environments. The standard configuration provides a 2 m cable length, while the Q5 suffix denotes a 4‑pin Euro‑style quick‑disconnect with a 150 mm pigtail; the device supports up to 3.5 m sensing distance in retroreflective/polarized mode. This makes it suitable for object presence/absence detection on conveyors, packaging lines, and other automation systems that require reliable sensing in challenging environments.
