Allen-Bradley 803-A4R

The Allen-Bradley 803-A4R Rotating Cam Limit Switch is engineered for precise control in machinery with repetitive operating cycles, making it an essential component for industrial applications. Designed to withstand harsh environments, this durable switch features a "Style A" configuration that allows for bi-directional shaft rotation at speeds of up to 150 RPM. It offers versatile cam duration settings ranging from 14 to 346 degrees, accommodating various operational needs. With four independent cam-roller assemblies, it reliably actuates 25A control circuits while housed in a type 1 industrial enclosure. Adjustments to internal timing and dwell settings can be made easily via angular degree scales, ensuring optimal performance tailored to specific applications.
