Absolute Encoder


Absolute encoders are position feedback devices that report absolute positional information. An absolute encoder generates a unique code for each position. Absolute encoders do not lose position when power is removed. Since each position is unique, true position verification is available as soon as power is up. It is not necessary to initialize the system by returning to home base.


  • Single-turn Absolute Solid Shaft Encoder

In a single turn encoder, the output codes are repeated for every revolution of the encoder shaft. There is no mechanism to indicate whether the encoder had made one revolution or several revolutions. All that is output is the relative position. Single turn absolute encoders are used when full range of positioning in the application is not greater than one full revolution (360 degrees) of the encoder shaft – an example is rotary table positioning.
