| 摘要 |
The invention relates to a high-resolution capacitive proximity sensor (11) with high-quality haptics and optics, said proximity sensor having a ceramic disk, behind which electrode sectors (18) are located. The ceramic disk is the base (13) of a flat pot (12) which is produced integrally in a ceramic injection molding process. Defined surface structures of the operating surface (14) on the pot base (13) are used in particular for tactile user guidance, while illuminated regions of the pot base (13) are used for optical user guidance, the pot base being axially accessible from the outside. The sensor circuit (16), which is placed in the pot (12) behind the electrode sectors (18), facing away from the operating surface, is surrounded by an electric conductor (27) in order to dissipate electrostatic charges, said conductor preferably being designed as an elastic buffer against the radial assembly environment. |
