The SHG-TT is
Newall's most popular incremental encoder and is compatible with the
majority of DROs and controls. The SHG-TT provides a differential quadrature
output at RS232 TTL levels. The periodic reference mark is synchronized
with the A & B signals.

Reference Marker
The diameter of the precision ball bearings making
up the signal conditioning elements of the scale defines the reference
marker location. A reference marker
generates each time the reader head travels one ball bearing pitch (0.5").
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.
