Abstract
A sensor arrangement for position sensing comprises a first magnetoresistive element () and a second magnetoresistive element (). A magnetic field source () provides a magnetic field with a first magnetic pole (N) and a second magnetic pole (S). The magnetic field source () is arranged between the first magnetoresistive element () and the second magnetoresistive element () with the first magnetic pole (N) facing the first magnetoresistive element () and the second magnetic pole (S) facing the second magnetoresistive element (). The first magnetoresistive element () is arranged in the magnetic field and provides a first output signal (R) dependent on a position of the first magnetoresistive element () relative to the magnetic field source (). The second magnetoresistive element () is arranged in the magnetic field and provides a second output signal (R) dependent on a position of the second magnetoresistive element () relative to the magnetic field source (). A measurement unit is configured to determine a position of the magnetic field source () relative to the first and the second magnetoresistive elements () dependent on the first output signal (R) and the second output signal (R).
