  • Publication number: 20110101964
    Abstract: A magnetic encoder element for use in a position measurement system including a magnetic field sensor for measuring position along a first direction is disclosed. The encoder element includes at least one first track that includes a material providing a magnetic pattern along the first direction, the magnetic pattern being formed by a remanent magnetization vector that has a variable magnitude dependent on a position along the first direction. The gradient of the remanent magnetization vector is such that a resulting magnetic field in a corridor above the first track and at a predefined distance above the plane includes a field component perpendicular to the first direction that does not change its sign along the first direction.
