A contact-free electrical connector arrangement is provided for transferring inductive energy from a primary connector component to a secondary connector component, comprising a pair of connector components each including a housing containing a chamber, a ferrite core arranged in the chamber, and a coil arranged in the chamber for cooperation with the core. An input cable supplies electrical energy to the coil contained in the housing of a primary one of said components, and an output cable removes inductively-transferred energy from the coil contained in the housing of a secondary one of said components. According to an operating method of the invention, a parameter is measured at the primary coil for interrupting the energy supply when the secondary component is not present.
