Incremental Linear Scale

lf400 

The LF400 series is a high accuracy, high repeatability slim-line scale designed for applications on CNC machine tools where display steps of up to 0.1μm are required.

These linear scales have a thermal behaviour similar to steel or cast iron.

Accuracy grades of ±5μm or ±3μm per meter traverse are available.
