Claim:
1. A method of fabricating a proximity sensor comprising: mounting a lead within an opening of a substrate; extending a sensor wire that extends from the lead through the opening in the substrate; depositing a base electrically non-conductive layer with a cure in place process onto the substrate and around the sensor wire; encapsulating the sensor wire within an electrically conductive layer deposited onto the base non-conductive layer with a cure in-place process, wherein an end of the sensor wire is held within the electrically conductive layer; applying a cover non-conductive layer over the conductive layer with a spray deposition process; and removing a portion of the non-conductive layer to expose a portion of the electrically conductive layer.
