Banner Engineering QS18VN6AF100Q Photoelectric Sensor

The Banner Engineering QS18VN6AF100Q is a compact all‑purpose photoelectric sensor from Banner’s World‑BEAM QS18 family, designed for reliable detection with fixed‑field background suppression. It uses a 660 nm visible red LED to sense targets from 1 mm up to a maximum 100 mm, with an adjustable cutoff from 20 to 100 mm. The device ships with a 2 m (6.5 ft) cordset and operates on 10–30 V DC, delivering a four‑wire output. The VN6 AF100 suffix indicates a 100 mm sensing range variant with a background‑suppressing field and an NPN output configuration. Its 18 mm housing fits into tight spaces, offering robust performance in cluttered environments where background interference can be an issue. The 660 nm LED provides consistent detection across typical target colors and materials. The sensor supports either dark‑on or light‑on operation depending on wiring, making it versatile for mounting and control across automation tasks.
