Many shops will be will more willing to replace a single defective scale on an existing DRO vs. replacing the entire system, if that will get them up and running. Newall's DSG and DMG ...
At Stanford’s SLAC Linear Accelerator Laboratory in Menlo Park California, we find the two-mile long linear accelerator, also known as the Linac. The Linac is used to drive a Coherent Light...
SHG-PV Linear Encoder 
The SHG-PV provides a differential quadrature output at 5-28V levels. The quadrature output is equivalent to the input DC voltage. SHG-PV will accept 5-28VDC input.
Examples:
- If the encoder is supplied with 5VDC, the output will be 5v quadrature.
- If the encoder is supplied with 24VDC, the output will be 24V quadrature.

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
