Difference Between Absolute & Incremental Encoder?


Recommended Posts

Hello AB2005


An absolute encoder can be used to find the absolute position whereas an incremental encoder is used to show how much you have moved.

You can sometimes use an incremental encoder to get an absolute position provided that you always begin at a calibrated home point.

Thank you Marke


Still some confusion.

What is the inside/designing difference between these two encoders? For example, I have worked only with Incremental Encoder till now. I know that this encoder produces square wave type pulses in two channels A and B. we use these pulses in PLC for calculating the position of anything else. What about absolute encoder?
