Capacitive proximity and/or contact sensor and electrically conductive plastic body for such a sensor |
摘要 |
A capacitive proximity and/or contact sensor has an electrically conductive plastic body, which is disposed between an electrically insulating cover plate and an electrically conductive contact surface of a carrier plate disposed at a distance therefrom. The contact surface can be connected to a gating circuit, through which a change in a capacitance of a condenser formed by the cover plate, the plastic body and the contact surface as a result of proximity and/or contact of a contact region of the cover plate by an element, having a potential different to the potential of the contact surface, can be ascertained and evaluated. The plastic body is configured as a plug-in and/or clamp part and by plugging-in or clipping on the or by clamping on the carrier plate is connected form lockingly and/or force lockingly to the latter and thus to the contact surface.
