Encoder Questions

could someone please tell what the difference is between incremental and absolute encoders

Basic differance:


Incrimental encoder:
outputs a pulse stream as it rotates. Basically just an on off on off on off, etc. Good for determining speed and distance.

Absolute encoder:
outputs a binary number called greycode. for example, an 8 bit absolute encoder will have 8 outputs each corrisponding to a bit in an 8 bit binary number. i.e. 10010110. This number corrisponds to a specific point in the rotation. Useful if you want to keep track of the position of a rotating object.

thank you for the information. Is there anybody out there that has a encoder that is 24v input an 24v output with just a single channel

Try these on for size.

Most of the encoder manufacturers make a single channel 24VDC supply encoder. Pick your favorite and go.
