Abstract
A linear or angular position sensor system comprising a magnetic structure for generating a magnetic field, and a sensor device movable relative to the magnetic structure. The sensor device comprises a plurality of sensor elements for measuring at least two characteristics of said magnetic field, and a processing circuit for determining a linear or angular position of the sensor device relative to the magnetic structure in accordance with a predefined function of these characteristics (e.g. components or gradients). The magnetic structure comprises one or more grooves, having a shape and size which can be described by a limited set of parameters, having values optimized to reduce a maximum error between the actual position of the sensor device, and the calculated position based on said predefined function, by at least a factor of 2.
