Product information "Optical Scale - Incremental GVS202S"
Incremental optical scale with stainless steel measuring support particularly suitable for synchronized press brakes
Characteristics:
- Reader head guided by a self-aligned and self-cleaning sliding carriage with spring system
- Resolutions up to 0.1 μm; accuracy grade up to ± 1 μm
- Adjustable cable output
- Reference indexes at coded distance or selectable every 10 mm along the entire measuring length, with Zero Magneto Set device
- The adjustable cable output and the selectable zero references make the scale SYMMETRIC and applicable, in the same version, to both columns of the press brake
- Various possibilities of application, with double-effect joint or steel wire
- Option: safety limit switches, positionable at both ends
