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
