Banner Engineering Q40AW3LPQ1 Photoelectric Sensor

The Banner Engineering Q40AW3LPQ1 Photoelectric Sensor is a polarized retro (retroreflective) detector in the EZ-BEAM Q40 Series designed for rugged, washdown-ready environments, delivering reliable presence sensing at up to 6 meters. It operates on 20–250 VAC with 50/60 Hz input and provides a SPST solid-state output via a micro 4-pin integral Quick Disconnect for compact, straightforward wiring. Built to withstand harsh conditions, the unit carries IP69K and NEMA 6P protection, making it suitable for demanding production lines and environments where moisture or debris is a concern. A visible red LED indicates sensing status, and the polarized retro mode requires a reflector for operation, which supports dependable detection on conveyors, packaging lines, and other automated equipment in tight spaces.
