Product information "Optical Scale - Incremental GVS600"

Optical scale with glass measuring support (grating pitch 20 μm). Particularly suitable for CNC machines.

Characteristics:

Innovative device inside the scale for the disposal of liquids coming from inefficient filtering systems.
Adjustable connecting cable output.
Reference indexes at coded distance, or at constant step, with predetermined or selectable positions.
Small size, to allow installation in narrow spaces.
Available with 1 Vpp and Line Driver output
