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 are round or disk-shaped and have evenly-spaced holes or markings around their perimeter

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

Linear encoders sense and digitize linear position change for positional measurement and feedback to control systems

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

Rotary positioning stages are devices with tables or shafts that may be rotated to any angular position. They may be driven or simple slides

Rotary tables are used to position items so that they can be machined, worked, or assembled

Digital encoders convert coded information into a familiar or uncoded format

Encoder and resolver signal conditioners accept encoder and resolver measurements and convert or condition these signals into digital data or suitable levels. 

Intermittent duty rotary solenoids convert axial motion into rotary stroke and are rated for on-off applications at less than 100% duty cycles. Like other types of solenoids, they convert electrical energy into mechanical power

Electric rotary actuators drive components rotationally via electromagnetic power. They typically have control and indexing capabilities

Pneumatic rotary actuators use pressurized air to rotate mechanical components

Linear position sensors, all types, is a general search form for all linear position / displacement detection product areas.

Rotary indexing tables are used to index components in defined, angular increments so that they can be machined, worked, or assembled in multiple operations. Tables can have fixed or adjustable indexing angles

Rotary switches move in a circle and can stop in several positions. There are two basic styles: single-deck and multi-deck
