Patent ID: 8461829

Claim:
A sensor unit ( 100 ), said sensor comprising: an Hall or magnetoresistive angle sensor ( 1 ) detecting around its longitudinal axis ( 10 a ), includes a magnetically sensitive face surface portion and a sensor element ( 4 ) proximal to a face surface ( 2 a ) which is fixed in place; and at least one magnet unit ( 50 ) disposed so that its magnetic field permeates the angle sensor ( 1 ), and field lines of at least one encoder magnet ( 50 a ) of the at least one magnet unit ( 50 ) extend parallel to a sensitive plane ( 4 ′) of the sensor element ( 4 ) wherein the encoder magnet is rotatable; and a magnetically conductive shielding ( 101 ) made of ferromagnetic material including at least one sensor shielding fixed in place and an encoder shielding rotatable together with the encoder magnet ( 50 ) wherein said sensor shielding ( 101 a ) is disposed closer than 6 mm to said sensor element ( 4 ), and the material of said sensor shielding ( 101 a ) has a coercitive field strength HC<5 A/cm.
