ABSTRACT:
A linear analog rotary 360 degree magnetic position sensor assembly for sensing the position of rotating objects. A magnet having a varying width is mounted to a magnet disc. A flux return disc is mounted on a shaft opposed to the magnet disc. The magnet generates a magnetic field in an air gap between the discs. A magnetic field sensor such as a hall effect sensor is positioned in the gap and operates to provide an output signal representative of the magnetic field density as the shaft and disc rotate. The output signal changes magnitude in relation to the relative position of the magnet with respect to the magnetic field sensor.
