摘要:
An encoder device for use in a magnetic sensor arrangement, comprising: a metallic ring having a set of clearances in a ferromagnetic material, wherein said clearances are arranged around a circumference of the metallic ring, wherein the metallic ring is configured to generate an oscillating magnetic induction in a nearby magnetic sensor upon rotation of the metallic ring, wherein the metallic ring is made of at least one flat and strip-like sheet metal material, two ends of which are joined to form a loop.
