Product Description
The Allen Bradley 803-B44RHRA is a Style "B" Rotating Cam Limit Switch (modified from groups 1 and 2) featuring four independent cam operators and single pole double throw snap action contacts rated for 10A continuous current across four circuits. It has a maximum shaft speed of 150 RPM and is housed in a Type 1 (general purpose) and Type 4/13 (dust-tight, water-tight, and oil-tight) enclosure. The "RH" designation indicates a Group 1 modification, specifically a right-hand shaft extension instead of the standard left-hand. This model also includes a 40:1 gear ratio for speed reducers and offers adjustable cam durations between 14 and 346 degrees, along with internal dwell and timing adjustments that must be performed while the device is stationary.
Is Your Device Showing These Signs?
The Allen Bradley 803-B44RHRA suffers from common failures including coil burnout due to overvoltage or surge events, resulting in operational failure of the pilot device. Contact degradation occurs from repetitive use or high inrush currents, causing increased resistance and potential welding. Mechanical wear affects the plunger and spring mechanism, impeding proper actuation and consistent performance. Environmental factors such as excessive dust or moisture ingress accelerate corrosion and insulation breakdown, leading to premature failure. Replacement of the coil, contacts, or entire unit restores functionality.
