Title:
CAPACITIVE DISTANCE SENSOR
Document Type and Number:
WIPO Patent Application WO/2012/031728
Kind Code:
A3
Abstract:
The invention relates to a capacitive distance sensor (2). The distance sensor (2) comprises a sensor element (4) having an electrically conductive, elongated, flat sensor area (16) which in turn contains a number of holes (18). The sensor area (16) is completely surrounded by an electrically non-conductive insulating body (14), with the result that the insulating body (14) completely covers the edge regions (22) of the holes (18). The sensor element (4) is produced, in particular, by first of all making the holes (18) in the sensor area (16). In a subsequent step, the sensor area (16) is completely encased by the insulating body (14) which also completely fills the holes (18) in the sensor area (16).
