ABSTRACT:
Device capable of detecting the rotational speed of two elements in relative such as the support elements of a vehicle wheel, in particular the rings of the roller bearing for the support the vehicle wheel, characterized in that an initial deflector or ring integral with the rotating ring of the bearing carries twin magnetized rings with pairs of poles of opposite sign, between which a magnetic sensor carried by a second deflector or support integral with the fixed ring of the bearing being is operatively inserted, the magnetic sensor being located between the n polar expansions, the number of which conforms to the pairs of opposing poles of twin magnetized rings.
