Abstract
An anti-pinch sensor (10,13,40,45) with an associated evaluation circuit (33,48) is disclosed, which is suitable in particular for recognizing an obstacle in the way of an actuating element (e.g., 9) of a motor vehicle (1). The anti-pinch sensor (10,13,40,45) comprises a sensor body, which contains a sensing electrode (17), for generating an external electric field with respect to a counter-electrode (25), and a pressure sensor (34,34′) decoupled from the sensing electrode (17), for detecting a mechanical pressure.
