Banner Engineering QS186LEQ8 Photoelectric Sensor

Banner Engineering QS186LEQ8 World‑BEAM QS18 Series Laser Emitter is a through‑beam, 4‑pin M12 QD device that pairs with QS18 receivers to create long‑range photoelectric sensing for industrial automation. Operating on 10–30 VDC and classified as a Class 1 laser emitter, it projects a visible laser beam across up to 15 m (about 49 ft) in opposed‑mode configurations, enabling precise alignment and reliable non‑contact detection. The QS186LEQ8 uses the European 4‑pin QD suffix “Q8” for compatible quick‑disconnect cabling and is part of Banner’s QS18 All‑Purpose family, designed to be used with compatible receivers to deliver robust sensing on conveyors, packaging lines, and other applications where easy field installation and dependable beam‑based detection are required.
