Rotary Shaft Encoder Selector Guide
- Wide variety of models to suit most applications.
- All models are available with a ball bearing on the shaft.
- Sleeve bushing options with "no-torque" or shaft torque are available to provide the correct "feel" for front panel human interface applications.
- US Digital offers several external cable drivers to convert single-ended outputs to differential (for models that do not support differential output).
- Shaft 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.
