ABSTRACT:
A signal transmitter supplies a contact closure type signal having a DC level to an electromagnetic coil inductively disposed around a magnetic core. The coil produces a corresponding magnetic flux which is, in turn, detected by a flux detector such as a Hall effect semiconductor element. The detector applies a signal corresponding to the detected magnetic flux to a signal receiver.
