Product Description
The Allen-Bradley 803-A9 is a robust, 9-circuit rotating cam limit switch designed for heavy-duty industrial machinery with cyclical operations where motion is linked to shaft rotation. It uses a rotating cam to actuate circuits, offering adjustable timing and dwell time (14-346 degrees) via cam lobe positioning. This Style A device features a spring-loaded cam roller, a 150 RPM shaft with oversized ball bearings, and 9 adjustable cam assemblies. Its normally-closed (NC) contacts are rated for 25A with an 1800 VA MAKE/BREAK power rating. The 803-A9 operates between -30 to 66C, stores between -30 to 93C, comes in a NEMA Type 1 enclosure for indoor use, has a left-hand shaft extension, weighs 15.9 kg, and measures 12.25 x 5.69 x 7.88 inches.
Is Your Device Showing These Signs?
Allen Bradley 803-A9 push buttons commonly exhibit issues such as contact degradation leading to intermittent or failed circuit continuity. Operators report problems with mechanical binding of the actuator, preventing proper switch operation. Field technicians often address corrosion on terminal connections, resulting in increased resistance and signal loss. Replacement of worn or damaged diaphragms is a frequent repair to maintain NEMA enclosure ratings and prevent environmental ingress. Troubleshooting frequently involves verifying proper voltage and current ratings to prevent premature component failure due to electrical overstress.

Our Repair Process for the
803-A9
Our repair process for Allen Bradley 803-A9 push buttons begins with a thorough inspection to diagnose contact degradation, mechanical binding, terminal corrosion, and diaphragm integrity. Technicians verify circuit continuity and address any contact degradation to ensure proper switch operation. Mechanical binding is resolved through careful adjustment and lubrication of the actuator. Corrosion on terminal connections is meticulously removed, and connections are tightened to eliminate resistance and signal loss. Worn or damaged diaphragms are replaced to maintain NEMA enclosure ratings and prevent environmental ingress. Voltage and current ratings are verified to prevent electrical overstress, ensuring component longevity.
