SHG-TC Incremental Linear Encoder Newall's SHG-TC linear feedback encoder reference markers allow the controller to acquire absolute position by moving the encoder systems across two uniquely spaced reference markers.

By using its internal absolute position count the encoder can mimic the distance coded index marks that are generated by glass scales. An index pulse is generated at uniquely spaced intervals in the range of 4 to 10mm, varying by 20-micron increments.

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.
