Abstract
A thin, metallic sensor ring for rotational sensing systems wherein protrusions formed on the periphery of the ring are constructed so as to interrupt an electromagnetic flux emitted by a sensing device mounted in fixed relation to the ring, whereby rotation of the ring may be detected. The protrusions are formed without removing any metal from the ring, preferably by a stamping or drawing operation. Slits may be provided in the ring to facilitate the formation of the protrusions. The ring may be partially encapsulated in a plastic mounting adapter to facilitate mounting thereof on a rotating shaft or hub.
