This document describes the technical data and features of the Quick Assembly Two and Three Channel Optical Encoders. These encoders have two or three channels and support quadrature output with optional index pulse. Features include quick and easy assembly, no signal adjustment required, availability of external mounting ears, low cost, resolutions up to 1024 counts per revolution, small size, operating temperature range of -40°C to 100°C, TTL compatibility, and single 5V supply.
The Agilent HEDM-550x/560x series are low‑cost two‑channel optical incremental encoders with optional external mounting ears. They provide high reliability, up to 1024 counts per revolution, and operate over a wide temperature range.
The document includes features, mechanical dimensions, electrical characteristics, recommended operating conditions, and mounting guidelines for quick assembly onto motor shafts.
