Abstract:
A position sensor, comprising:(a) a housing;(b) a movable shaft, disposed at least partially in the housing, for being moved in accordance with the position to be sensed;(c) a first sensor component, mounted on the shaft so as to rotate with the shaft, for emanating an internally or externally generated excitation signal; and(d) a second sensor component mounted in the housing so as not to rotate relative to the housing, the second sensor component comprising:(i) a first printed wiring board for producing a raw signal induced by the excitation signal in response to a rotary displacement between the first sensor component and the second sensor component;(ii) a second printed wiring board for converting the raw signal into a position-indicating signal; and(iii) a magnetic shield disposed between the first printed wiring board and the second printed wiring board;the movable shaft being secured to the first sensor component so that movement of the movable shaft causes the rotary displacement.
