HEDM-55xx/560x & HEDS-55xx/56xx Quick Assembly Two and Three Channel Optical Encoders Data Sheet

2022-10-27

●Description
■The HEDS-5500/5540, HEDS-5600/5640, HEDM-5500/5540 and HEDM-5600 are high performance, low cost, two and three channel optical incremental encoders. These encoders emphasize high reliability, high resolution, and easy assembly.
■Each encoder contains a lensed LED source, an integrated circuit with detectors and output circuitry, and a codewheel which rotates between the emitter and detector IC. The outputs of the HEDS-5500/5600 and HEDM-5500/ 5600 are two square waves in quadrature. The HEDS-5540/5640 and HEDM-5540 also have a third channel index output in addition to the two channel quadrature. This index output is a 90 electrical degree, high true index pulse which is generated once for each full rotation of the codewheel.
■The HEDS series utilizes metal codewheels, while the HEDM series utilizes a film codewheel allowing for resolu-tions to 1024 CPR.
■These encoders may be quickly and easily mounted to a motor. For larger diameter motors, the HEDM-5600, and HEDS-5600/5640 feature external mounting ears.
■The quadrature signals and the index pulse are accessed through five 0.025 inch square pins located on 0.1 inch centers.
■Standard resolutions between 96 and 1024 counts per revolution are presently available. Consult local Avago sales representatives for other resolutions.
