Kit Incremental Encoder Selector Guide

Our most popular stepper motor encoders, the E-series optical incremental encoder offers motor design engineers precise position measurement with reliability in the parts-per-million range.

  • All encoder models offer multiple mounting options.
  • US Digital offers multiple adapters to convert single-ended encoder signals to differential.
  • Push-on hubs provide fast assembly and symmetrical weight distribution for high RPM applications.
  • Incremental encoder models are part of our standard inventory and are available for same-day shipping*.

*Orders placed before 11:00 AM (PST) ship the same day.
