Devices and instruments for sensing and measurement of angular motion, speed, and position; includes encoders, resolvers, synchros and similar devices.
Absolute Rotary Encoders (268 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 (361 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.

Rotary Encoder Disks (20 suppliers)
Rotary encoder disks are round or disk-shaped and have evenly-spaced holes or markings around their perimeter.

Rotary Position Sensors (200 suppliers)
Rotary position sensors include potentiometers, resolvers and a variety of magnetic and capacitive technologies. Sensors are designed for angular displacement less than one turn or for multiturn displacement.
