Product Description
The Allen-Bradley 803-F512RH, a discontinued (2007) 803 series rotating cam limit switch, is a heavy-duty industrial device used in repetitive-cycle machinery like bottling or molding machines to provide precise control through independently adjustable, externally timed switching circuits actuated by cams on a rotating shaft. It features five circuits, can be mounted at any angle, operates in either direction, has a right-hand shaft extension, measures 177.8 x 82.6 x 312.7 mm, weighs approximately 5.9 kg, and functions in temperatures from -30 to 66 degrees Celsius.
Is Your Device Showing These Signs?
The Allen Bradley 803-F512RH encounters common failures such as coil burnout due to overvoltage or sustained inrush current, contact degradation from repetitive high current switching, and mechanical wear affecting armature movement. Troubleshooting includes verifying coil resistance, inspecting contact surfaces for pitting or erosion, and assessing the mechanical linkage for binding or damage. Replacement of the coil, contacts, or entire starter assembly is required to resolve these issues and restore motor control functionality. Proper overload protection and routine maintenance are essential to prevent these failures.
