Motion feedback devices providing position and velocity information to closed-loop control systems.
Absolute Rotary Encoders (287 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 (385 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.

Linear Encoders (269 suppliers)
Optical Encoder Disks and Strips (21 suppliers)
Optical encoder disks and strips are components of rotary and linear encoders, respectively. They are usually made of metal, plastic, glass, or paper. Optical encoder disks and strips have evenly-spaced holes or markings around their perimeter or length.

Rotary Encoders (446 suppliers)
Rotary encoders convert the angular position of a shaft or axle to an analog or digital code. There are two types of rotary encoders, absolute and incremental encoders, which can be controlled by various technologies which include mechanical, optical, magnetic and fiber optic.
