The encoder has at least one magnetoresistor (120, 220, 320, 322, 324, 326) and the magnetic support has a succession of magnetized regions (242, 342, 442), characterized in that the magnetic encoder also has a flux guide (154, 254, 354, 454), which has reading pole pieces (256, 256', 356) separated by at least one air gap (252, 352, 452) having a length (g) less than the smallest spacing of the magnetized regions.
