Device for detecting an obstacle in the opening area of a mobile closing element

摘要

Device for recognizing an obstacle in the opening region of a moving closing element comprises a sensor electrode and a base electrode joined together using an electronic component. A testing voltage is applied to the sensor electrode and the base electrode. An evaluation unit prepares a control signal for a drive which moves the closing element when there is an electrical contact with the electrodes. Device for recognizing an obstacle in the opening region of a moving closing element comprises a sensor electrode (20) and a base electrode (21) joined together using an electronic component (22). A testing voltage is applied to the sensor electrode and the base electrode. The electrodes are further apart in a second operating mode. An evaluation unit (40) prepares a control signal for a drive which moves the closing element when there is an electrical contact with the electrodes.
