Banner Engineering QS18VN6LPQ8 C01 Photoelectric Sensor

QS18VN6LPQ8 is Banner Engineering’s World-BEAM QS18 Series polarized retroreflective photoelectric sensor, designed for compact, reliable object detection in packaging lines and conveyors. It uses a 630 nm visible red emitter with polarized retroreflective reception to detect targets at up to 3.5 m (12 ft) and is specified for 10–30 V DC operation with a solid-state NPN output (complementary), supporting both dark-on and light-on configurations. The sensor features an integral 4-pin M12 quick-disconnect connector for quick wiring, all housed in the 18 mm QS18 form factor for tight installations. This model’s specifications are corroborated by Banner’s QS18 literature and by distributor listings from Mouser and DigiKey, which note the 3.5 m range, 10–30 V DC supply, and NPN output, making it well-suited for inline sensing on conveyors, package-assembly stations, and other automated material-handling tasks where polarization helps mitigate background clutter and surface variation.
