Incremental Feedback Encoders for CNC/PLC: SHG-TT Linear Encoder
SHG-TT Linear Encoder
The SHG-TT is Newall's most popular incremental encoder and is compatible with most major brands of PLC and CNC controls. The SHG-TT provides a differential quadrature output at TTL levels. The periodic reference mark is typically used for homing purposes.

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.
