Abstract

Es wird ein Einklemmsensor(1,1',1'), insbesondere zum Erkennen eines Hindernisses im Wege eines Stellelements eines Kraftfahrzeugs, angegeben, der einen Sensorkörper (2), eine im Sensorkörper (2) angeordnete erste Messelektrode (4) zur Erzeugung eines ersten äußeren elektrischen Feldes (12) gegenüber einer Gegenelektrode (9) und eine im Sensorkörper (2) der ersten Messelektrode (4) benachbart angeordnete, elektrisch getrennte zweite Messelektrode (6) zur Erzeugung eines zweiten äußeren elektrischen Feldes (14) gegenüber der Gegenelektrode (9) umfasst. Dabei sind die Messelektroden (4, 6) derart ausgebildet, dass das erste äußere elektrische Feld (12) eine größere Reichweite als das zweite äußere elektrische Feld (14) aufweist. Weiter wird eine zur Auswertung des Einklemmsensors (1,1',1') geeignete Auswerteschaltung angegeben. Die Detektionssicherheit eines derartigen Einklemmsensors (1,1',1') wird durch eine oberflächliche Verschmutzung oder durch eine oberflächliche Wasserbenetzung (10) nicht gestört.
