Abstract
An electromagnetic connector well suited for use in harsh environments. The connector used an E-core or C-core magnetic members for coupling power such as from a backplane to a module mounted on the backplane and using I-cores for coupling signals to and from the module. Separation of the power and signaling allows optimization of each coupling without compromise in performance of each function. Use of I-cores for signal coupling provides efficient use of space, with the use of E-cores or C-cores providing maximum power coupling to the module in a minimum space. Various aspects of exemplary embodiments are disclosed.
