Carrier ring for an encoder
A carrier ring for an encoder assembly includes a suspension device with resilient members. The encoder assembly includes a sensing device, such as a sensor head, for scanning directly toward a rotatable encoding member positioned on the carrier ring. The carrier ring is intended to be installed on a shaft of a machine.
