Absolute rotary encoder

Solid shaft encoders
Incremental encoders generate a certain number of pulses per revolution. The number of pulses is a measure of the distance moved (angular or linear).
Hollow shaft encoder
Hollow shaft encoders are always used when reduced installation length is required or when precision is important where the drive is subjected to high acceleration.
Absolute encoders
Singleturn
Absolute encoders provide a specific numerical value (code value) for each angular position.
Multiturn
Multiturn encoders not only detect angular positions but also distinguish between several revolutions.
