More Information
Summary:A sensor device for a motor vehicle for detecting an operation by a user, including at least one capacitive sensor which has a sensor electrode, which is coupled to a control and evaluation circuit. The sensor electrode has a primary detection section which extends adjacent to a detection region into which a body part of a user is moved for operation purposes. The sensor electrode is accommodated in a housing which runs, in sections, between the sensor electrode and the detection region. The sensor electrode is provided, in the region of the primary detection section, for increasing the electrical field in sections, with recesses and/or openings which are delimited by edges, so that a length at the limiting edges, which length is increased in relation to a continuous electrode area, is present in the primary detection section.
