Product Description

The Allen Bradley 803-PL4X is a durable rotating cam limit switch designed for heavy-duty control of rotating machinery. It monitors shaft rotation and speed, triggering contact actuation at specific points in the machine's cycle. Measuring 28" x 21" x 21" and weighing 15 lbs (6.8 kg), it features 2-12 independent cam operators, three 25A contacts, and three 10A contacts. Available with or without cams, it includes a 25A N.C. double break contact and allows for easy dwell adjustment from 11 to 360 degrees, supporting shaft speeds up to 400 RPM. Applications include assembly, packing, steel forming, punch presses, injection molding, and waterway gate lock operations.

Is Your Device Showing These Signs?

The Allen Bradley 803-PL4X pilot light frequently exhibits issues such as burned-out incandescent lamps requiring replacement, corrosion on the terminal block leading to poor electrical connections, and physical damage to the lens or housing from impact. Troubleshooting includes verifying proper voltage input to the pilot light, inspecting the continuity of the lamp filament, and ensuring secure connections at the terminal block to resolve intermittent operation. Replacement of the entire unit is necessary if the housing is cracked or the lens is severely damaged, compromising the NEMA rating and environmental protection.
