Banner Engineering Q85BB62LP Photoelectric Switch

The Banner Engineering Q85BB62LP Photoelectric Switch is a polarized retroreflective sensor in Banner's Q85 Series that detects a polarized retro target from 80 mm up to 4.6 m. It operates on 10-48 V DC and provides a bipolar pair of outputs (one NPN and one PNP) through a four‑wire terminal wiring chamber. The device emits a visible red 680 nm sensing beam, uses LED indicators for status, and offers adjustable sensitivity via a potentiometer; it features a fast 1 ms response time and 250 µs repeatability. Built for harsh environments, it carries IP67 protection and a NEMA 4X rating, with a thermoplastic rectangular housing and a 4‑pin connection. It switches with a light/dark operate mode, and the operating temperature range is -25°C to 55°C. Typical uses include conveyors, packaging lines, and other manufacturing processes where polarized retroreflective sensing is advantageous.
