Product Description
The Allen-Bradley 803-P4LH is a robust "P" style Bulletin 803 rotating cam limit switch designed for durability and longevity in heavy-duty operations. Featuring a heavy-duty steel base and solid cast iron side plates, it has 4 circuits rated at 25 Amps and a maximum shaft speed of 400 RPM. It includes an N.C. double break contact, accommodates 2 to 12 independent cam operators with adjustable cam segments (11-349 degree duration), and incorporates vibration-resistant spiral locks and locking nuts. The switch operates by actuating contacts via cams mounted on a rotating shaft, with circuit activation timing determined by cam position. It features conduit entrances on both sides, a standard right shaft extension (modifiable to left), and potential for external adjustment sprocket modification. The 803-P4LH utilizes a Type 1 enclosure, providing protection against light, dust, and contact with live parts.
Is Your Device Showing These Signs?
The Allen Bradley 803-P4LH suffers from common failures including contact degradation leading to operational failure, coil burnout due to overvoltage or sustained inrush current, and mechanical wear affecting plunger movement and overall switch responsiveness. Expect issues with the limit switch's inability to properly signal position due to environmental contamination affecting internal components. Resolve these problems through contact cleaning or replacement, coil replacement with properly rated components, and thorough inspection and lubrication of mechanical linkages to ensure correct functionality and extend the lifespan of the switch.
