Product Description
The Allen-Bradley 803-PL10LH is a heavy-duty Rotating Cam Limit Switch (Bulletin 803 Style P) designed for machinery with repetitive cycles where switch shaft rotation corresponds to machine motion, suitable for applications like steel forming, packaging, and waterway gate control. It features a shaft-mounted cam that actuates contacts as the shaft rotates, offering 10 circuits with a cam-opened 25A normally closed (NC) contact and up to 10 independently adjustable cam assemblies with adaptable segments. The switch has a 400 RPM shaft speed, a factory-modified left-hand shaft extension, and a keyway for machine connection. A spring-loaded cam roller actuates the circuit when contacting the upper cam segment and deactivates it when passing the lower segment; dwell time (cam activation duration) is determined by the upper cam segment's size. Timing, adjustable from 11 to 349 degrees based on cam position relative to the keyway, along with dwell time settings, dictates machine operation and control. The 803-PL10LH offers low-cost, high-speed internal dwell and timing adjustments during machine stops, comes in a NEMA Type 1 enclosure, operates between -22 and 150 degrees Fahrenheit, stores between -22 and 200 degrees Fahrenheit, weighs approximately 13.2 kg (29 lbs) with fewer cams, and measures 483.3 x 181 x 138.1 mm (19.04 x 7.12 x 5.44 inches).
Is Your Device Showing These Signs?
The Allen Bradley 803-PL10LH limit switch commonly experiences issues such as contact degradation leading to signal failure, spring fatigue causing inconsistent actuation, and physical damage to the housing compromising environmental protection. Troubleshooting includes verifying continuity across contacts, assessing spring tension for proper return, and inspecting the enclosure for cracks or breaches. Replacement of worn contacts, springs, or the entire limit switch assembly resolves these problems, ensuring reliable position sensing and control in industrial automation applications.

Our Repair Process for the
803-PL10LH
Our repair process for the Allen Bradley 803-PL10LH limit switch begins with a thorough troubleshooting procedure that verifies continuity across contacts to identify signal failures, assesses spring tension to detect actuation inconsistencies, and inspects the housing for any physical damage compromising environmental protection. Upon identifying the fault, we proceed with the necessary repair, which may involve replacing degraded contacts to restore signal integrity, exchanging fatigued springs to ensure consistent actuation, or substituting the entire limit switch assembly if the housing is compromised. This comprehensive approach guarantees the restoration of reliable position sensing and control within industrial automation applications.
