Abstract (en)
[origin: WO2008006424A2] The invention relates to an anti-pinch sensor (1,1',1"), especially for detecting an obstacle in the path of a regulating element of a motor vehicle, said sensor comprising a sensor body (2), a first measuring electrode (4) which is arranged in the sensor body (2) and is used to produce a first outer electrical field (12) in relation to a counter-electrode (9), and an electrically separated second measuring electrode (6) which is arranged adjacently to the first measuring electrode (4) in the sensor body (2) and is used to produce a second outer electrical field (14) in relation to the counter electrode (9). The measuring electrodes (4, 6) are embodied in such a way that the first outer electrical field (12) has a larger range that the second outer electrical field (14). The invention also relates to an evaluation circuit suitable for evaluating an anti-pinch sensor (1,1',1"). The detection reliability of such a clamping sensor (1,1',1") is not affected by dirt or water (10) on the surface thereof.
