Incremental Feedback Encoders for CNC/PLC: SHG-VS Linear


SHG-VS Linear Encoder

The SHG-VS linear encoder is intended for use with the SCC-200 module. The SCC-200 will output a ~1Vpp sine/cosine signal with a single reference marker. The encoder has a series of four selectable reference markers spaced every 25.4mm. The reference selected for the output reference is dependent on the rotational alignment of the scale relative to the reader head upon installation.

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.
