Abstract
On a railroad car handbrake system the main handbrake shaft, used to turn the chain, is utilized during its rotation to drive a target object to a magnetic sensor. The target object may be driven by cam plates, gears, screw mechanisms or the like and may be a magnetic or ferromagnetic object. The sensor system disclosed is rugged and easily adapted to existing handbrake systems.
