Product Description
The Allen-Bradley 803-B84X is a robust, 8-circuit rotating cam limit switch with a double shaft extension, designed for repetitive machine cycles where shaft rotation corresponds to motion. Featuring adjustable dwell time and timing (when stationary), it operates bidirectionally up to 150 RPM. Its spring-loaded cam-roller assembly provides adjustable cam durations from 14 to 346 degrees and utilizes standard 10 Amp snap-action N.O./N.C. contacts. Suitable for storage between -30 and 93 degrees Celsius and operation between -30 and 66 degrees Celsius, the switch exhibits typical shaft torques of 7, 0.5, and 3 inch-pounds depending on cam roller position. Weighing 36 pounds, its Type 1 enclosure allows mounting in any orientation.
Is Your Device Showing These Signs?
The Allen Bradley 803-B84X suffers from common failures including contact degradation leading to operational malfunction, coil burnout causing system downtime, and mechanical wear affecting switch responsiveness. Expect issues with the operating mechanism due to repetitive use, resulting in sluggish or failed actuation. Environmental factors contribute to corrosion on electrical connections, increasing resistance and disrupting signal integrity. Replacement of worn components and thorough cleaning of contacts restores functionality.
