Abstract
A capacitive distance sensor includes a sensor element having an electrically conductive, elongated, flat sensor area which in turn contains a number of holes. The sensor area is completely surrounded by an electrically non-conductive insulating body, with the result that the insulating body completely covers the edge regions of the holes. The sensor element is produced, in particular, by first of all making the holes in the sensor area. In a subsequent step, the sensor area is completely encased by the insulating body which also completely fills the holes in the sensor area.
Claims19
A capacitive distance sensor, comprising:
- a sensor element, the sensor element comprising:
- an electrically conductive, elongated, flat sensor;
- a plurality of holes formed in the flat sensor, the holes extending from an upper surface of the flat sensor to a lower surface of the flat sensor;
- and
- an electrically nonconductive insulating body completely enclosing at least the upper surface and the lower surface of the flat sensor and the insulating body extending into the holes from the upper surface and the lower surface so as to form a uniform body completely covering inner surfaces of the holes.
