Abstract (en)
[origin: WO2009048910A2] A sensor assembly comprises a capacitive proximity sensor (1) mounted to a shaped surface of a body, such as the internal surface (10) of a vehicle bumper (11), to sense the presence of external objects. The sensor comprises a dielectric film substrate (2) having front and rear major surfaces that, in use, face respectively outwards and inwards of the body, a sensor conductor (6) on the front major surface, and a guard conductor (8) on the rear major surface to provide an electrical shield for the sensor conductor. The surface (10) to which the sensor (1) is mounted is one that does not provide a substantially flat area for direct attachment of the sensor, at least in the sensor conductor region, and, with a view to ensuring the correct functioning of the sensor, the sensor mounting is designed to inhibit the ingress and retention of water/dirt between the sensor and the shaped surface, and to enable a major part of the sensor substrate to be maintained in a substantially flat condition at least in the sensor conductor region.
