QS18VN6LP is Banner Engineering’s World‑BEAM QS18 Series polarized retroreflective photoelectric sensor. It emits a 630 nm red light, detects targets at a 3.5 m range, and operates on 10–30 V DC with an NPN transistor output rated up to 100 mA. Housed in an 18 mm‑diameter M18‑style body with a pre‑wired 2 m cable, it is designed for compact mounting in automation cells. For retroreflective sensing you must supply a reflector, as no reflector is included with the unit.
