Abstract
A code wheel (32) is rotatable with a vehicle steering wheel (12). A magnet (78) mounted on a rotatable driven component (34) indicates the number of revolutions of the code wheel (32). A sensing device (74) is provided to sense a flux field provided by the magnet (78). The magnetic flux field varies relative to the sensing device (74) as the driven component (34) is rotated by the code wheel (32).
