SHG-AF Linear Encoder
This protocol is proprietary to Fanuc and available on all of their control systems. The controller makes a request for positional data and the encoder has to respond correctly with data within a strictly controlled time state. Developed to meet a wide range of feedback applications, the
SHG-AF absolute linear encoder provides a true absolute position immediately upon power-up. 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.

Quick and Easy Installation
The design of these linear encoders allow installment in almost any position, unlike glass-scale linear encoders, which usually need to be installed with the lip seal facing downwards to prevent contamination. Self-aligning fixing brackets allow virtually effortless scale mounting, needing only a single hole for each set of brackets.
