Overview
The Banner QS18VN6DQ8 is a diffuse-mode photoelectric sensor from Banner Engineering’s WORLD-BEAM QS18 series. Built for industrial automation and factory floor applications, this sensor delivers 450 mm sensing range with 10-30 VDC NPN solid-state output. The M12 integral quick-disconnect (QD) connector ensures fast, tool-free installation and replacement. Diffuse sensing mode makes it ideal for detecting opaque objects without requiring a retroreflector.
