Banner Engineering Q4XTBLAF300-Q8 Laser Contrast Sensor

Q4XTBLAF300-Q8 is a rugged stainless steel laser sensor from Banner Engineering’s Q4X series that delivers reliable short‑range distance and contrast sensing in harsh environments. It measures distance in the 25 mm to 300 mm range using a Class 1 visible red laser and employs background/foreground suppression to distinguish targets from background, making it well suited for object presence and positioning tasks on fast production lines. The unit is powered from 10–30 V DC and provides two discrete outputs (bipolar): 1 NPN and 1 PNP, via an integrated 5‑pin M12 quick‑disconnect connector, all within a compact rectangular housing designed for mount flexibility. This sensor carries IP67, IP68, and IP69K protection and operates from −10 to 50 C, with a max ambient light tolerance of 5000 lux and remote teach for field adjustments. In Banner’s own documentation, the Q4XTBLAF300‑Q8 is described as a laser‑adjustable field model with a minimum sensing distance of 25 mm and a maximum sensing distance of 300 mm, making it suitable for applications like packaging, material handling, and automated inspection where precise, durable distance or contrast sensing is required.
