Incremental Feedback Encoders for CNC/PLC: MHG-VP Linear
MHG-VP Linear Encoder
The MHG-VP linear encoder is intended for use in conjunction with Newall's SCC-200 module. The SCC-200 will output a ~1Vpp sine/cosine signal making it ideally suited for CNC and other control feedback.

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.
