Incremental
Incremental Encoders provide sine-cosine or quadrature square wave feedback signals that allow for direct integration to servo driven applications. We supply encoders from Newall for more information click here

Absolute
Absolute Encoders provide a true absolute position immediately upon power-up within one revolution.  The encoder does not use batteries or static memory to retain the positional data.True position can be reacquired once power is applied, regardless of duration or power-off movements.
