Banner Engineering Corporation SLM80B6Q Slot Sensor

Banner Engineering's SLM80B6Q is a rugged nickel-plated metal fixed-distance slot sensor from the SLM Series, designed for harsh industrial environments. It detects presence across an 80 mm (3.15 in) slot width and utilizes a fixed-distance optical slot design for reliable mounting and operation. Powered by a 10–30 V DC supply, the device provides bipolar outputs—1 NPN and 1 PNP—through a 4‑pin M8 integral quick-disconnect connector for straightforward wiring. The nickel-plated metal housing enhances durability in challenging conditions, making it suitable for slot-based sensing on conveyors, presses, and various automation equipment. The SLM80B6Q is the QD version of the family, enabling quick field connections without a separate cable, and it serves as a robust alternative to mechanical limit switches in fixed-distance slot sensing applications.
