Abstract
A package for a magnetic field sensitive element, such as a magnetoresistor, includes at least two planar layers of a relatively stiff ferromagnetic material which is also electrically conductive. The layers have opposed edges which are in closely spaced relation to form a narrow gap therebetween. A terminal tab is integral with and extends from each layer. A magnetic field sensitive element is on a surface of at least one of the layers and preferably extends across the gap to be on both layers. The magnetic field sensitive element has a pair of contacts each of which is electrically connected to a separate one of the layers. A permanent magnet is mounted on and insulated from the surface of the layers opposite the magnetic field sensitive element. A protective layer of an insulating material may cover the magnetic field sensitive element and the layers with the terminal tabs extending therefrom.
