Banner Engineering QH23SP6DL Photoelectric Sensor

The Banner Engineering QH23SP6DL is a compact, diffuse-mode photoelectric sensor designed for non-contact detection on industrial lines, powered from 10 to 30 V DC and offering a 30–300 mm sensing range in diffuse operation. It features a PNP transistor output capable of sourcing up to 150 mA and uses a visible red beam at 680 nm to simplify alignment; the model is part of Banner's QH23 family, known for miniature DC sensors with self-contained housings. The sensor ships with a 2 m (6.5 ft) long, 4-pin Pico QD cable, and the actual detectable range depends on target reflectivity, making it suitable for detecting parts on conveyors, in packaging lines, or other automation tasks where reliable diffuse sensing is required. The QH23SP6DL designation indicates a diffuse-mode configuration within the Q23/QH23 series, with a 10–30 V DC supply, 680 nm red emission, and a 30–300 mm nominal target range that supports straightforward alignment and consistent performance across a variety of industrial environments.
