1. A sensor bearing assembly comprising:
a bearing having an inner ring and an outer ring centered on an axis,
an impulse ring secured to the outer ring of the bearing,
a sensor device for detecting rotational parameters of the impulse ring, the sensor device including a sensor housing and at least one sensor element supported by the sensor housing and cooperating with the impulse ring, and
an annular spacer adapted to axially abut against a lateral face of the inner ring of the bearing,
wherein the sensor housing is fixedly secured to the spacer,
wherein the inner diameter of the spacer is equal to the inner diameter of the inner ring of the bearing,
wherein the outer diameter of the impulse ring is less than or equal to the outer diameter of the outer ring of the bearing,
wherein the sensor housing has a hollow interior having a volume,
wherein the at least one sensor element is mounted in the hollow interior, and
wherein the volume of the hollow interior is greater than a volume of the at least one sensor element.
