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.
