Abstract

The present invention discloses a two axes absolute linear positioning system (6), comprising a carrier (5), a first position sensor arrangement (1), a second position sensor arrangement (1), the first position sensor arrangement (1) and the second position sensor arrangement (1) each comprising a magnetic region (2) having a south pole and a north pole, and a magnetic field detector (3), wherein the first and the second magnetic regions (2) are arranged in a defined position with respect to the carrier (5), and wherein the orientation of the south pole and the north pole of the first magnetic region (2) is inclined to the orientation of the south pole and the north pole of the second magnetic region (2).
