Allen-Bradley 871C-DH1M8-D4 Inductive Proximity Sensor

Allen-Bradley 871C-DH1M8-D4 is a miniature inductive proximity sensor from Rockwell Automation, featuring an 8 mm diameter barrel and a 1 mm nominal sensing distance. Housed in nickel-plated brass and designed for DC operation, it provides a NAMUR output paired with a Micro QD quick-disconnect connection, making it well-suited for tight spaces on automation equipment. As a member of the 871C tubular sensor family, it enables non-contact detection of metal targets on compact conveyors, indexing machines, and machine frames where space is at a premium. Reports from multiple distributors indicate a switching frequency up to about 2000 Hz, which supports fast-cycle sensing, with options available for DC wiring to suit different installation needs.
