A sensor assembly is described herein. The sensor assembly includes a housing that includes an inner surface that defines a cavity within the housing, and a proximity sensor positioned within the cavity. The proximity sensor includes a first connector, a second connector, and a substantially planar sensing coil that extends between the first connector and the second connector. The sensing coil extends outwardly from the first connector such that the second connector is radially outwardly from the first connector.
