These particular transducers have two matched encoders: absolute and incremental.
This allows a high application flexibility, for any purpose. On request, special custom version can be developed. Typical application of these encoders is the keying on "Brushless" motors in which the "absolute" section describes the motor's strokes.
Max. incremental resolution is 2540 pulses/rev., the absolute one is 256 div./rev. equal to 8 bit (in according to those available for each model).
