Abstract: A system includes at least one hand-held power tool and at least one electrotechnical product. The power tool includes a housing with a handle, a drive motor arranged in the housing, and a first interface configured to receive information from at least one second external interface and/or to transmit information to the at least one second external interface. The housing of the hand-held power tool and a housing of the electrotechnical product each have a receiving opening. The first interface is removably arranged in a selected one of the receiving openings. The receiving openings are releasably sealed by corresponding covers. The covers close the housings to the outside.

Abstract: A magneto-resistive layer system, in which a layer arrangement is provided in an environment of a magneto-resistive layer stack working on the basis of the GMR effect or the AMR effect, in particular the layer arrangement generating a resulting magnetic field that acts upon the magneto-resistive layer stack. The layer arrangement has a first magnetic layer and a second magnetic layer, which are separated from one another by a non-magnetic intermediate layer and are ferromagnetically exchange-coupled via the intermediate layer. Furthermore, a sensor element having such a layer system is provided, particularly for the detection of magnetic fields with respect to their strength and/or direction.
