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.
