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

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

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

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

Digital encoders convert coded information into a familiar or uncoded format

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

Magnetic stripe card readers and encoders read and encode magnetic stripe cards, credit cards, etc

ID card readers and encoders are used to transmit personal information onto various forms of storage media and retrieve this data as needed

DC motors are most commonly used in variable speed and torque applications. They include brushless and gear motors, as well as servomotors.

DC servomotors are generally small and powerful for their size, and easy to control. Common types of DC servomotors include brushless or gear motors.

AC servomotors are responsive, high-acceleration motors typically constructed as permanent magnet synchronous motors.

Motion control systems contain matched components such as controllers, motor drives, motors, encoders, user interfaces and software. Components in these systems are optimally matched by the manufacturer

Servo drives provide electrical drive outputs to servo motors in closed-loop motion control systems where position feedback and corrective signals optimize position and speed accuracy.

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.
