ABSTRACT:
A generally planar shaped inductor is disclosed that is particularly adaptable for use in motion or position sensors. One inductor can function as a signal input unit and another as a pick up unit in an arrangement wherein both inductors are placed in a generally parallel juxtaposition for flux flow there between. A movable armature is located between the inductors to control the amount of flux transmission between inductors. The position of the armature relative to the inductors controls the output signal generated by the pickup inductor that are adapted to be converted into indications of displacements.
