A sensor including a bobbin including a first region adapted to receive windings and a second region defining a cavity formed in the bobbin. A first electrical terminal is coupled to the bobbin and disposed in the cavity and a second electrical terminal is coupled to the bobbin and disposed in the cavity. A wire including a wound portion wound about the first region. The wire is conductively coupled to the first terminal and the second terminal to provide an electrically conductive pathway from the first terminal to the second terminal. A magnetizable core is disposed at least partially within the wound portion and a magnet is positioned adjacent the magnetizable core. An overmolded shell defining an exterior surface of the sensor encapsulates at least the first region and the wound portion and contacts at least the wound portion.
