Abstract
A sensing mechanism includes a magnetic source, a magnetic flux sensor, a sensor backing on which the magnetic source and flux sensor are mounted, and a ferromagnetic target, where the magnetic source, magnetic flux sensor, and ferromagnetic target are positioned to form a magnetic circuit from the magnetic source to the target, from the target to the sensor, and returning to the magnetic source through the sensor backing.
