Incremental Feedback Encoders for CNC/PLC: MHG-TT Linear


MHG-TT Linear Encoder

The MHG-TT linear encoder is compatible with the majority of PLC and CNC controls. The encoder provides a differential quadrature output at RS422 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.
