Description:
The remote sensor assembly is designed to provide an interface between an electronic sensor
and mechanical input motion from the operator. A sensor is employed which provides a voltage
proportional to the shafts angular displacement. The remote body provides holes for mounting the
sensor to the remote and for mounting the remote to the host machine.
