<p>The sensor (11) generates capacitive measuring fields (12), and determines penetration of an object into the measuring fields. The measuring fields are pointed in a preset direction, and are electrically separated from each other, where electrical signals are produced by the change of the measuring fields to determine characteristic approach of the objects to be moved on the measuring sensor. The measuring sensor is connected with an electrical operated evaluation unit, via which the changes of the measuring fields measured by the measuring sensors are evaluated and processed.</p> |
