Heidenhain's Inductive Rotary Encoders

The inductive rotary encoders of the ExI 1100 series are available in versions whose mating dimensions are the same as those of common types of resolvers. The ExI 1100 rotary encoders with EnDat 2.1 interface feature an inductive scanning method, with which the single-turn resolution is 18 bits (262144 position values per revolution). The single-turn position value is produced by electronics already integrated in the encoder and is transferred as purely digital information to the electronics over the bidirectional EnDat interface.
