CxZ Geared Cam Limit Switches

Series 51 Geared Cam Limit Switches can map a wide range of shaft rotations to the angular displacements of the installed cam discs. These cam discs actuate electro-mechanical switches. They are used where angles or distances cannot be limited directly by switchgear, but only indirectly on the basis of the measured angle of rotation. A classical example of this application involves limiting the hook lift of a crane hoist.
