Abstract
A rotation detection set comprises an encoder washer rotatable around a rotation axis, at least one sensor adapted to detect a rotation parameter of the encoder washer through an air gap, a support member for holding the sensor with respect to the rotation axis and a mounting member for immobilizing the support member with respect to a fixed structure. The mounting member is made of one piece of magnetic material and has a first wall located on the same side of the air gap as the encoder washer and a second wall located on the same side of the air gap as the sensor whereas a magnetic body of the encoder washer, the air gap and the sensor are located in a volume defined by the mounting member between the two walls.
