ABSTRACT:
A data coupler for use in transmitting data between mechanical parts which have a common axis and which are in relatively close engagement. The parts are adjustable relative to the other along the common axis. The data coupler includes an elongate housing having a longitudinal axis extending parallel to the common axis of the parts and is slidable relative to the parts during adjustment of the parts. A data source A and a data receiver B are spaced apart lengthwise. An axially short solenoidal coil is provided at each of the data source A and the data receiver B. An axially long solenoidal coil extends lengthwise throughout a major portion of the length of the housing and arranged relative to the axially short solenoidal coils, to be one overlying the other, at least in part, throughout the range of relative slidable adjustment of the housing
