DEVICE FOR THE DETECTION OF AN ACTUATION ANGLE OF AN ELEMENT ROTATABLE ABOUT A SHAFT

摘要

A device for detecting an actuation angle of an element rotatable or pivotable about a shaft of the mentioned type. The device includes a sensor unit configured to emit an electrical signal depending on an angle of rotation and including an annular permanent magnet non-movably connected to the rotatable or pivotable element. The sensor includes a stationary Hall sensor array having two or more Hall sensors disposed at an angular distance about the annular permanent magnet, wherein an individual Hall sensor located in a linear zone defined by the movement of the rotatable or pivotable element is selected by a microcontroller according to a current position of the rotatable or pivotable element.
