Product information "Magnetic Scale - Incremental GVS215"

Incremental magnetic scale with pole pitch 2+2 mm.
Particularly suitable for synchronized press brakes.
Reader head guided by a self-aligned and selfcleaning sliding carriage with spring system.
Resolutions up to 1 μm.
Repeatability ± 1 increment.
Reading without contact.
Adjustable cable output.
Selectable reference indexes, every 10 mm along the entire measuring length, with device for generating the reference indexes.
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.
