Position sensor with integrated signal-conditioning electronics on a printed wiring board

A position sensor, such as a rotary position sensor, includes the signal-contitioning electronics in the housing. The signal-conditioning electronics are disposed on a printed wiring board, which is assembled with another printed wiring board (25) including the sensor windings to provide a sub-assembly (39). A mu-metal shield (31) is interposed between the printed wiring boards to prevent magnetic interference. The sub-assembly (39) is disposed in the sensor housing adjacent to an inductor board (15) which turns on a shaft. The inductor board (15) emanates an internally or externally generated excitation signal that induces a signal in the sensor windings. The induced signal represents the rotary position of the inductor board (15) relative to the sensor winding board.
