A contact assembly includes a conductive body, a dielectric layer and a conductive layer. The conductive body extends along a longitudinal axis between a mating end and a mounting end. The dielectric layer is disposed over the conductive body between the mating end and the mounting end. The conductive layer is disposed over the dielectric layer and is separated from the conductive body by the dielectric layer. The conductive layer, the dielectric layer, and the conductive body form a capacitive element.
