Avago Enables Unprecedented Miniaturization of Motor Encoding Systems with Industry’s Smallest Three-Channel Reflective Encoders

A standard reflective encoder module contains two digital output channels for direction sensing, with another module required for indexing purposes. For motion feedback applications requiring high-resolution measurement, an external interpolation device had previously been necessary. The Avago AEDR-850x reflective encoders integrate an LED light source, photodetecting and interpolator circuitry, and the three channels in a single package with a 3.95-mm-by-3.40-mm footprint. With high resolution encoding of 304 lines per inch (12 lines per mm), the compact, highly-integrated modules enable a new level of miniaturization for applications where size and space are primary concerns.
