Incremental Linear Scale


The LS300 series is a slim-line scale designed for typical applications on manual machine tools such as milling machines or lathes where display steps of 10μm or 5μm are sufficient.

Jig boring, grinding and metrology applications normally require display steps of 1μm or less. Linear encoders for these more stringent requirements typically feature accuracy grades of ±5μm per meter traverse, and are described on the CNC Linear Encoders page.
