Hollow center angular position sensor
An angular position sensor is disclosed. The angular position sensor has a cylindrical magnet holder that has a base portion attached to a top surface of a shaft and a magnet holding portion extending from the base portion. A magnetic coding is arranged on the outer surface of the magnet holding portion that establishes a magnetic field. A sensor base encircles the base portion of the magnet holder and supports magnetic field sensors that are fixed on an arc-segment. The arc-segments partially overlap so that output signals of the magnetic field sensors are indicative of the angular portion of the sensor base relative to the shaft.
