HEDM-55xx/560x&HEDS-55xx/56xx Quick Assembly Two/Three Channel Optical Encoders Data Sheet
The Avago HEDM‑55xx/560x and HEDS‑55xx/56xx series are low‑cost, high‑performance two‑ and three‑channel optical incremental encoders. They provide quadrature outputs with optional index pulses and are designed for quick and easy assembly on motor shafts.
The document includes theory of operation, mechanical and electrical characteristics, recommended operating conditions, mounting guidelines, and typical interface options, helping users select the right resolution, install the encoder, and integrate it into control systems.
| Resolution | up to 1024 counts per revolution |
|---|---|
| Operating Temperature | -40 °C to 100 °C |
| Shaft Axial Play | +0.25 mm |
| Maximum Speed | 30,000 RPM |
The encoders support resolutions up to 1024 counts per revolution.
Avago Technologies states the encoders are not recommended for safety‑critical use such as ABS braking or life‑support systems.
The index output is a 90‑degree electrical pulse generated once per full rotation of the codewheel.
