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.


  • Multi-turn Absolute Encoder

In a multi turn absolute encoder, the output is unique for each shaft position through every rotation up to x number of revolutions.
Multi turn absolute encoders are used when a full range of positioning in the application requires multiple turns of the encoder shaft – an example of this is lead and ball screw applications.
