Custom circuitry performs field-orientation detection and filtering while providing an analog output proportional to angular position. Features of the sensors include <±0.5% independent linearity; 30 to 360° electrical measurement angles; a lifespan of more than 50 million movements, repeatability of <0.03% of output signal range; and operation in –40 to 85°C. The sensors are not affected by static or dynamic shaft loads of up to 20 N in both radial and axial directions.
