Incremental magnetic encoder

An incremental magnetic encoder defining an encoder axis and comprising a fixed body and a body movable with respect to the fixed body along at least one direction of encoding;

• one of the bodies, called first body, comprising:
• a first support comprising N magnetic elements arranged along the direction of encoding according to a homogeneous pitch PO and defining a magnetic alternation along the direction;
• the other body, called second body, comprising:
• a second support comprising K*M magnetic elements arranged inhomogeneously along the direction of encoding opposite the N magnetic elements, the K*M magnetic elements forming M groups of K magnetic elements, each of the M groups comprising an initial magnetic element of said group, the initial elements of the M different groups being spaced from each other along the direction of encoding according to a homogeneous pitch P1, the K−1 magnetic elements of each group being spaced from the initial magnetic element of said group according to variable pitches Pi looped back over a predetermined extent along the direction of encoding;
• at least one magnetic detector arranged opposite the first support and configured for quantifying each movement of the movable body along the direction of encoding, wherein, within each group, the magnetic elements are uniformly spaced from each other.
