APPROACH DETECTION DEVICE

摘要

An approach detection device for motor vehicles includes a sensor carrier and a sensor electronic system disposed in a receiving space therein. The device includes a capacitive approach sensor coupled to an evaluation circuit which has a capacitive surface for detecting approaches. The device is mounted via a carrier frame, including a fastening section, to a vehicle body part and includes a detection opening. The sensor carrier is fastened to the carrier frame such that the active capacitive surface of the sensor is oriented toward the detection opening. A receiving space is defined by the detection opening and the sensor carrier and is formed in the region of the detection opening. A sealing element is disposed in the receiving space on the sensor carrier.
