Banner Engineering QL55M6XD50BQ Photoelectric Sensor

The Banner Engineering QL55M6XD50BQ Luminescence Sensor is a self-contained unit in Banner’s QL55 Series that detects luminescent targets with a 370 nm black UV LED and a 4 mm beam spot, offering a maximum sensing range of 75 mm. It runs on 10–30 V DC and provides both a selectable NPN/PNP discrete output and a 0 to 5.5 V analog output, with an integral four-pin M12 quick-disconnect. The sensing head uses a glass lens and supports light/dark operate, while the housing is rated IP62 and compatible with NEMA 4X environments. Operating temperature ranges from -10 to 55 °C and humidity up to 85% at 50 °C. Remote Teach is not enabled on this model. Model QL55M6XD50BQ is listed as INACTIVE by Banner, reflecting its position within the luminescence sensor family; nonetheless, its specifications align with the QL55 Luminescence series’ self-contained microprocessor-based design and UV-illumination approach for detecting luminescent materials on surfaces, labels, or packaging. This sensor is suitable for applications where luminescent features must be detected despite challenging reflectivity, and it integrates with Banner amplifiers and fiber optic accessories via the M12/QD connection for compact automation layouts.
