  • Method, sensor, and printed circuit board for sensing position or motion of a shaft
    Patent number: 9784596
    Abstract: The present disclosure presents a method, a sensor comprising printed circuit board (PCB), and a sensor PCB for a capacitive sensor for sensing position or motion of a shaft comprising an electrically conducting part. The method and the sensor utilize the sensor PCB that comprises a mounting hole through which the conducting part of the shaft can be mounted, at least one capacitor electrode formed to the printed circuit board, wherein an electrode surface of the electrode extends parallel to a center axis of the mounting hole and faces the center axis.
