A sensor for a medical device including a plurality of sensor segments. Each of the plurality of sensor segments can include a layer of magnetically-permeable material and a layer of electrically-conductive material disposed on the layer of magnetically-permeable material. In an example, the layer of magnetically-permeable material can be arranged in a partially-annular shape. The sensor segments can include an electrical connection formation that extends transverse to the layers of magnetically-permeable material and electrically-conductive material. The electrical connection formation can be electrically coupled with the layer of electrically-conductive material. The plurality of sensor segments can be electrically coupled with each other through an electrical coupling of the respective layer of electrically-conductive material of each sensor segment with the electrical connection formation of another sensor segment.
