Title: Anti-pinch sensor

Abstract: An anti-pinch sensor, particularly for detecting an obstacle in the path of an actuating element of a motor vehicle is provided, having a sensor body, a measuring electrode, which is disposed in the sensor body and to which a measuring potential can be applied, a calibrating electrode, which is electrically disconnected and disposed in the sensor body adjacent to the measuring electrode, and a control unit. The control unit controls the measuring electrode and the calibrating electrode such that the measuring potential and the calibrating potential are equal in a measuring phase, and differ from each other in a calibrating phase.
