Banner Engineering Q4XTBLAF300-Q8 Photoelectric Sensor

Banner Engineering's Q4XTBLAF300-Q8 is a rugged, all‑purpose photoelectric sensor from the Q4X family designed for harsh industrial environments. It covers a sensing range of 25 to 300 mm (0.98 to 11.81 in), suitable for detecting small parts, features, or presence along conveyors and automation stations. The device operates on 10–30 V DC, drawing up to 28 mA, and includes protection against short circuits and reverse polarity. Digital outputs are NO/NC in a bipolar arrangement (1 NPN; 1 PNP), so it can interface with a wide range of controllers and PLCs; the Q8 variant integrates a 5‑pin M12 quick‑disconnect connector for quick field wiring. The sensor’s compact stainless steel housing measures 43.5 × 18 × 57.5 mm, providing durability in challenging environments and compatibility with nearby tooling. It emits red light at 655 nm and supports background/foreground suppression to improve reliability when targets appear at different distances or against assorted backgrounds; the response time is typically under 1.5 ms, enabling fast cycling on productive lines. The Q4XTBLAF300-Q8 is a compact, rugged sensing solution with dual digital outputs, a built‑in QD connector, and a 25–300 mm range for general presence/absence sensing on a variety of industrial applications.
