A composite annular encoder (15) for a bearing with information sensor (16), comprises an annular metal support (21) of L-shaped cross section with a plane radial part (21a) and an axial part (21b), and a annular element (22) produced as a single piece made from thermoplastic material, which annular element is constituted by a radial part (22a) which includes the multipole ring (22b) and is overmolded onto the plane radial part (21a) of the metal support, and by an axial retaining part (22c) overmolded onto the outer surface of the axial part (21b) of the metal support. The metal support has, on its axial part, anchoring points (21c, 21d) for the overmolding of the axial retaining part (22c) of the annular element made from thermoplastic material, enabling the thermoplastic annular element and the metal support to be rendered axially and circumferentially integral.
