Heidenhain's 700 Series Encoders

700 Series encoders have a thin design and a large hollow shaft of up to 25.4 mm, often allowing these encoders to be mounted directly on a motor's shaft without an intermediate adapter. They have a dual set of heavy-duty bearings and a well-encapsulated enclosure. Electrical interfaces include TTL, 1VPP, HC HTL, HTL and RS-422, each adapted to different frequencies, temperatures and cable lengths.
