ABSTRACT:
A search coil assembly for an inductive search device of the transmitter/receiver type is described having advantages relative to manufacture, repeat accuracy and sensitivity in operation. This is made possible by the utilization of printed-circuit board technology in search coil construction in which electrically conductive windings in the form of a conductor band of circuit tracks are arranged side-by-side at the periphery of partial areas on a carrier layer common to the partial areas.
