I can't find for sure what AoA probe was actually fitted to the AF447, but a likely candidate is a Thales C16291AA which has a catalog range of +/- 60 degrees - but this "Local Angle of Attack" gets corrected before use, so the limit is likely in the corrections/compensations.
Note this AoA probe has recently been subject to an AD to correct a manufacturing issue - excess oil which could impede motion at low temperatures. I don't know exactly what triggered this AD, the Perpignan A320 had Goodrich 0861ED probes, two of which probably froze at altitude due to water ingress during cleaning.
