This rolling bearing assembly (2) comprises a rolling bearing (4) with an inner ring (8), an outer ring (6) and several rolling bodies (10) between the inner and outer rings, at least one sensor (30) adapted to detect a rotation parameter of a first ring (8) with respect to a second ring (6) of the rolling bearing and a support member (40) holding the sensor (30) in position with respect to the rolling bearing (4). The support member (40) holds the sensor (30) in a position such that at least one connecting pin (34, 36, 38) of the sensor (30) extends in a volume (46) defined by the support member (40) and adapted to accommodate an electrical connector (100).
