Patent ID: 8415946

Claim:
An arrangement for absolute determination of a linear position or of a rotation position expressed by an angle of two bodies adapted to be displaced or rotated relative to one another, comprising: a first body having a scale with a plurality of magnetic segments that alternate in polarity in a measurement direction; a second body having at least two spaced-apart magnetic-field-sensitive sensors for obtaining an angle of the magnetic field at each of the magnetic-field-sensitive sensors; and an evaluation unit for determining from the obtained angle of the magnetic field at each of the magnetic-field-sensitive sensors a phase difference that corresponds with the position being measured, wherein the scale comprises a single magnetic track comprising multiple groups, each of the multiple groups having at least two magnetic segments, with a length of the at least two magnetic segments in the measurement direction in at least one group being identical to one another, and lengths of the magnetic segments of different groups being different from one another.
