Abstract
Anti-pinch sensor (2, 2′, 2″), in particular for detecting an obstacle in the path of an actuator of a motor vehicle, having a first measurement electrode (6) and having a second electrically isolated measurement electrode (7) spaced a distance from the first measurement electrode (6), wherein the first measurement electrode (6) is designed to generate an external electric field (17) with respect to the second measurement electrode (6), and wherein the first and second measurement electrodes (5, 6) are elastically supported relative to an electrically isolated ground electrode (8). In addition, a sensor device (1) having such an anti-pinch sensor (2, 2′, 2″) is disclosed. The anti-pinch sensor (2, 2′, 2″) is suitable as both a contactless and a tactile sensor. Detection of surface deposits of contaminants or water is easily possible.
