Banner Engineering QS18AP6LP-93093 World-Beam Photoelectric Sensor

Banner Engineering’s World-Beam QS18AP6LP-93093 is a compact, all‑purpose photoelectric sensor in the QS18 series that uses polarized retroreflective sensing for reliable presence detection in tight spaces. It detects targets at a max range of 3.5 m (11.5 ft) and is powered from 10–30 V DC with a PNP discrete output, configured for light or dark operate. The rectangular ABS housing, 18 mm in diameter, mounts via an M18 style bracket and carries IP67 and NEMA 4X ratings for demanding industrial environments. A 2 m RJ11 quick-disconnect pigtail is included for straightforward wiring, and the sensing beam operates at 630 nm (red LED) for clear alignment. Key performance specs include a fast 0.6 ms output response time and 150 µs repeatability, making it suitable for high-speed conveyors or packaging lines. The sensor supports four-pin discrete I/O, and an indicator LED provides at-a-glance status. Operating temperature ranges from -20 to 70 C, ensuring reliable performance across typical factory floors, while its polarized retroreflective mode helps differentiate targets from background surfaces. This model is ideal for general-purpose automation tasks that require a compact, rugged, easy-to-wire sensor with a straightforward RJ11 connection and a robust sensing capability up to 3.5 meters.
