Banner Engineering QS18EP6DQ8 Photoelectric Sensor

The Banner Engineering QS18EP6DQ8 is a World‑Beam QS18 series diffuse‑photoelectric sensor in a compact rectangular housing with up to 800 mm detection range in diffuse mode. It operates on 10–30 V DC and provides a four‑pin connection with a PNP output, configurable for dark‑on or light‑on sensing. The unit supports quick‑disconnect options and uses a 940 nm infrared emitter for diffuse sensing, with typical response time under 0.6 ms and a DC operating current up to 100 mA (no‑load around 35 mA). The QS18EP6DQ8 variant is specified as IP40, suitable for general industrial environments, and the QS18 family offers cable options of 2 m (6.5 ft), 9 m (30 ft), or 150 mm (6 in) with an M8 quick disconnect connector. Built with an ABS plastic housing and a PMMA lens, it provides a robust, compact sensor suitable for mounting on conveyors, packaging lines, or automation cells where simple, reliable diffuse detection is required.
