摘要： This sensor unit (6) for sensing the angular position of a rotatable element (42) with respect to a fixed element (44) comprises an encoder element (62) which is fast with the rotatable element (42), adapted to generate magnetic field variations as a function of its angular position, and a sensing element (640) fast with the fixed element (66), adapted to sense the magnetic field variations. The sensing element (640) is supported by a sensor body (64) which is mounted in a shielding casing (66) fast with the fixed element (44). This shielding casing (66) comprises at least one flux concentrator (668, 670) adapted to deflect away from the sensing element (640) an interfering magnetic field in which the sensor unit (6) operates.

摘要： This sensor unit (8) for sensing the angular position of a rotatable element (4) with respect to a non-rotatable element (2) comprises an encoder (82) fast in rotation with the rotatable element (4), a sensor body (84) fixed with respect to the non-rotatable element (2), including at least one sensing element adapted to sense the angular position of the encoder (82), a casing (85) in which the sensor body (84) is housed, and an output cable (94) for transmitting sensing data to a reception device. The casing (85) comprises a protruding portion (850) extending radially outwards from an outer peripheral wall (86) of the casing (85), said protruding portion (850) being adapted to accommodate the output cable (94). The protruding portion (850) comprises at least one claw (860a, 860b) which surrounds and clamps the output cable (94).
