Abstract
A protective housing and mounting apparatus for simultaneously protectively enclosing, and mounting to a given surface, a generally cylindrical capacitive-type proximity sensor having a substantially solid and unbroken external surface and an electrode member at one axial end thereof. The protective housing and mounting apparatus comprises a one-piece integrally formed member of a durable, moldable plastics material, including an end surface configured for complementary mounting upon a given surface and a protective body portion extending from this end surface for surroundingly housing an end part of the sensor proximate the axial end thereof at which the electrode member is located. The body portion has a cylindrical open-ended bore therein for receiving an end part of the sensor and this bore extends to a point closely spaced behind the end surface. A quantity of conductive material covers substantially all external surfaces of the body portion and a predetermined portion of the end surface away from the periphery thereof, such that there is no continuity of electrically conductive material between the end surface and the body portion surfaces. An arrangement is provided for establishing electrically conductive contact between the end surface conductive material-covered portion and the electrode of the sensor, such that the end surface conductive portion defines an electrode of selected size and configuration for the sensor.
