Banner Engineering QS18EK6XLPCQ8 Retroreflective Optical Sensor

Banner Engineering's QS18EK6XLPCQ8 World-BEAM QS18 retroreflective photoelectric sensor offers reliable part detection on conveyors and assembly lines, detecting objects up to 3 m (118 in) away with polarized coaxial retroreflective sensing and a 625 nm red beam for consistent performance across varied backgrounds. It runs on 10–30 V DC, uses a four-pin M12 quick-disconnect, and provides two configurable outputs (PNP/NPN) with light/dark operate, plus remote teach for easy alignment in tight spaces. The ABS rectangular housing with an 18 mm barrel houses a PMMA lens and status LEDs, is designed for rugged industrial environments with a NEMA 4X-rated enclosure, and features a teach button for quick setup. Key specs include a 0.4 ms response time, -40 to 70 C operating range, 100 ms power-up delay, 95% RH at 50 C maximum humidity, and clear object detection capability, making it well-suited for applications in packaging lines, material handling, and automated machinery where precise, fast sensing is required.
