Abstract
An incremental magnetic encoder is provided which defines an encoder axis and which as a fixed body and a body movable with respect to the fixed body along at least a first direction of encoding. One of the bodies, called first body, has a first ring extending along a first longitudinal direction coinciding with an encoder axis and a first circumferential direction perpendicular to the first longitudinal direction, and defining a magnetic alternation along the first direction of encoding. The other body, called second body, has at least one first notching tooth made of ferromagnetic or magnetic material arranged opposite the first ring, and a first pair of magnetic sensors arranged opposite the first ring and configured for quantifying each movement of the movable body along the first direction of encoding.
