Rotation angle displacement sensor has cylindrical yoke which includes four permanent magnets arranged such that two of them are separated by prescribed space interval between them

摘要

Permanent magnets (M1a,M1b,M2a,M2b) are arranged in the inner surface of cylindrical yoke such that magnets (M2a,M2b) are arranged opposing to magnets (M1a,M1b), at a distance (L) between them on one side of the yoke.
