Product Description
The Allen Bradley 803-P8 rotating cam switch, a heavy-duty Style "P" device, controls industrial machinery by correlating to shaft rotation and supporting repetitive, cyclic movements. It handles speeds up to 400 RPM and is used in applications like metalworking, packaging, and injection molding. Featuring 2 to 12 independent cam operators with 25A N.C double break contacts, it's available with or without cams and offers adjustable cam durations from 11 to 349 degrees. Timing adjustments are made internally by loosening cam bolts, rotating the cams to the desired position, and then retightening the bolts.
