HEDS-5640-E06

The HEDS-5640, 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 HEDS-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. These encoders may be quickly and easily mounted to a motor. For larger diameter motors, the 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.
