The MHG-TT linear
encoder is compatible with the majority of DROs and controls, either
directly using TTL differential quadrature output signal or the hybrid
version that gives a 1Vpp or 11µApp analog output.

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 (5mm).
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.
