Abstract
A transducer position sensing system, in a electromechanical drive, for determining transducer position. A sensor is mounted with a non-adjustable position and without absolute position accuracy, thereby lowering manufacturing costs. The position of the transducer at which the sensor switches states is accurately determined in a manufacturing test fixture and recorded in a permanent memory used by a drive controller. The drive controller can then accurately determine transducer position during subsequent initialization procedures.
