Abstract:
1. A method for producing a sensor unit for sensing the angular position of a rotatable element with respect to a fixed element, comprising, the fixed element being spaced from the rotatable element by a radial gap, an encoder element rotatably fastened to the rotatable element, adapted to generate magnetic field variations as a function of its angular position, and a sensing element fastened to the fixed element, adapted to sense the magnetic field variations, the sensing element being mounted on and connected to a printed circuit board mounted in a shielding casing fastened to the fixed element such that the shielding housing is configured to directly contact the printed circuit board to facilitate electrical communication therebetween, the shielding casing being configured to extend over the radial gap between the fixed element and the rotatable element and to enclose the printed circuit board except for a side of the printed circuit board facing the fixed element, the method comprising the step of earthing the shielding casing by electrically connecting it to a load discharging device of the printed circuit board.
