Encoder device for use in a magnetic sensor arrangement, comprising:
a metallic ring (26) with a set of clearances (32) in a ferromagnetic material, wherein
said clearances (32) are arranged around a circumference of the metallic ring (26),
wherein the metallic ring (26) is configured to generate an oscillating magnetic induction in a nearby magnetic sensor (24) upon rotation of the metallic ring (26),
characterized in that the metallic ring (26) is made of at least one flat and strip-like sheet metal material, two ends of which are joined to form a loop. |
