DescriptionThe HEDS-5500/5540, HEDS- 5600/5640, and HEDM-5500/ 5600 are high performance, low cost, two and three channel optical incremental encoders.
These HEDS-5500/5540, HEDS- 5600/5640, and HEDM-5500/ 5600 encoders emphasize high reliability, high resolution, and easy assembly.
Each HEDS-5500/5540, HEDS- 5600/5640, and HEDM-5500/ 5600 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 and 5640 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 resolutions to 1024 CPR. The HEDM series is nont available with a third channel index.These HEDS-5500/5540, HEDS- 5600/5640, and HEDM-5500/ 5600 encoders may be quickly and easily mounted to a motor.
For larger diameter motors, the HEDS-5500/5540, HEDS- 5600/5640, and HEDM-5500/ 5600 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 Agilent sales representatives for other resolutions.
