Condition Sensing Switches and Controls
Rotating Cam Switches
Bulletin 803 Rotating Cam Switches
Allen-Bradley Rotating Cam Limit Switches sense the movement of rotating machinery by initiating functions at various points of the machine's repetitive cycle. These heavy-duty industrial control circuit devices open and close contacts at various angles of machine shaft rotation. All styles actuate contacts by using cams mounted on a rotating shaft. Bulletin 803 Rotating Cam Limit Switches are available in six styles to fit numerous control requirements. Special modifications are available for custom applications.
The world-class quality line of Allen-Bradley Rotating Cam Limit Switches is designed and constructed for rugged applications. Quality construction requires very little maintenance when properly applied. Switch shaft assemblies rotate smoothly on long-life, precision bearings. All switches operate equally well rotating in either direction and can be mounted in any plane or angle. Each cam can be independently adjusted without affecting the other circuits. Contact dwell can be set from 11 to 360 degrees.
