Banner Engineering QL55M6XD50BQ Photoelectric Sensor

Banner Engineering's QL55M6XD50BQ is a self-contained luminescence photoelectric sensor in the QL55 family, designed to detect luminescent targets with a 4 mm beam and a sensing range up to 75 mm. It provides bipolar (NPN/PNP) outputs and includes an integral M12 quick-disconnect connector with a 4-pin configuration, plus an analog output option for combined discrete and analog signaling, all powered from 10–30 V DC. The sensor operates in light or dark mode, features a teach button for calibration, a glass lens, and a black ultraviolet LED beam at 370 nm to optimize luminescence detection, with a 0.25 ms response time. It is rated IP62 (NEMA 4X) and specifies an operating temperature of -10 to 55 °C and humidity up to 85% at 50 °C. Banner notes this model is obsolete and recommends contacting them for a suitable replacement, ensuring compatibility with your controller and luminescent target characteristics.
