Absolute Encoder

Incremental encoders and absolute encoders

Incremental and absolute encoders perform similar functions but have different outputs. Incremental encoders only generate pulses during operation by rotation of the shaft.

Absolute encoders measure the position continously as information of 1 and 0 independant whether the encoder moves or not. The exact position is recorded even if the power is turned off.

The structure of a clock explains the working of incremental and absolute encoders. The ticking of a clock corresponds to the incremental output. By counting the ticks it is possible to determine the time but you must have a starting point. The arm of an analogue clock should correspond to the abolute output, then you can read the time (information) directly.

You can change from a absolute to a incremental encoder without a problem. It would be necessary however to modify the software and hardware.
