Abstract
A capacitive angle sensor that is used preferably in motor vehicles includes a sensor housing ( ) having a cover ( ′) covering the sensor housing ( ). A stator ( ) and a rotor ( ) are positioned in the sensor housing ( ), each respectively including a ceramic plate and lying in a plane parallel to the other. The ceramic plates are preferably of an Al O ceramic. Printed electrode structures of electrodes ( ), as sensor capacitances and coupling capacitances ( ), are located on sides of the stator ( ) and of the rotor ( ) facing respectively outward. The electrode structures are printed on back sides of the ceramic plates, so that the electrodes ( ), upon assembly into the angle sensor ( ), are located on the sides of the stator ( ) and of the rotor ( ) that face respectively away from each.
