E-series Kit Incremental Encoder Selector Guide

Arguably the most popular stepper motor encoder in the world, US Digital's E-series optical incremental encoder gives motor design engineers precise position measurement at low cost. US Digital ships over 300,000 per year, with reliability in the parts-per-million range. 

  • All models offer multiple mounting options.
  • US Digital offers a number of external cable drivers to convert single-ended outputs to differential (for models that do not support differential output).
  • Push-on hubs provide fast assembly and symmetric weight distribution for high rpm applications.
  • All models are available from stock with fast shipment.
