Abstract
A parts handling device is provided having a movable carrier on which is disposed a plurality of coil wound magnet poles. At least one of the poles is wound and with an A.C. source so that its current or voltage is subject to changes in response to induced magnetic flux caused by its proximity to a ferro-magnetic material. The changes in current or voltage so induced is sensed by a low impedance device or a resonant circuit device and an electric signal is produced which is employed to convert said poles to D.C. excitement control the operation of the parts handling device.
