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
