Fuente: Wipo "Sensorization" A sensor device (100) for determining an absolute angular position (θ) of a magnetic source (110) having an inner magnet portion (111) being a magnetic dipole, and an outer magnet portion (112) being a multipole ring magnet, the sensor device being a single packaged device comprising: a first sensor group for measuring a first set of at least two magnetic field components or magnetic field gradients at a first sensor location (gc1); a second sensor group for measuring a second set of at least two magnetic field components or magnetic field gradients at a second sensor location (gc2) spaced from the first sensor location (gc1) by a predefined distance (ds); output means for outputting the first and second set of signals, or one or more signals derived therefrom. Said magnetic source (110). An angular position sensor system (120; 1420) comprising said sensor device and said magnetic source.
