HEDM-5500#B01

Quick Assembly Two and Three Channel Optical Kit Encoder

Currently Viewing:

The HEDS-5500/5540, HEDS-5600/5640, and HEDM-5500/5600 are high performance, low cost, two and three channel optical incremental kit encoders. These kit encoders emphasize high reliability, high resolution, and easy assembly.

Each kit 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 kit encoders are two square waves in quadrature. The HEDS-5540 and 5640 kit encoders 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 kit encoders series utilizes metal codewheels, while the HEDM kit encoders series utilizes a film codewheel allowing for resolutions to 1024 CPR. The HEDM series kit encoders are not available with a third channel index.

These kit 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 Technologies sales representatives for other resolution options.
