Motion feedback devices providing position and velocity information to closed-loop control systems.
Absolute Rotary Encoders (289 suppliers)
Absolute rotary encoders use optical, mechanical, or magnetic indexing for angular measurement. They do not lose their position after power-down, but instead provide absolute position upon power-up without requiring a home cycle or any shaft rotation.

Incremental Rotary Encoders (387 suppliers)
Incremental rotary encoders are multi-turn sensors that use optical, mechanical, or magnetic index-counting for angular measurement. They contain no absolute reference, but instead count relative to the turn-on position.
