The invention relates to a tachometer (10) for an aircraft wheel (R) mounted on an axle (E) so as to rotate about an axis (X) of rotation, the tachometer comprising a stator (20) that is intended to be attached to the axle (E) and a rotor (30) that is intended to rotate with the wheel. According to the invention, one of the stator or the rotor comprises at least one contactless sensor (23) having at least two measurement cells (28.1, 28.2) suitable for co-operating with a plurality of targets (37) carried by the other of the stator or the rotor in order to generate two signals (S1, S2) that are representative of a speed of rotation of the wheel, the measurement cells being angularly offset from one another about the axis (X) so as to detect a direction of rotation of the wheel by combining the two signals.
