The Banner Engineering QS18VN6LPQ8-79665 Photoelectric Sensor is a World Beam QS18 Series all‑purpose device that uses polarized retroreflective detection with a 630 nm visible red beam. It operates from 10 to 30 V DC, provides an NPN output, and offers a 3.5 m sensing range in polarized retroreflective mode. Bright status LEDs are visible from 360°, aiding quick diagnostics in production lines. With an 18 mm housing, this compact sensor is designed for tight spaces on conveyors and small-packaging applications while delivering reliable object presence sensing.
