ABSTRACT:
An encoder device for the determination of absolute angle or linear segments is described, with which the distance from the actual to the reference position is determined upon prompting and output via incremental signals. This encoder offers new functions for the incremental measuring system employed up to now. The transition to the absolute measuring system is also made possible according to requirements.
