GVS 219

Self-aligned absolute magnetic scale

  • Magnetic scale with pole pitch 2+2 mm and direct reading of the absolute position. Particularly suitable for applications on synchronized press brakes.
  • High-speed SSI-BiSS C (unidirectional) serial interface.
  • Option: 1 Vpp analog signal.
  • Reader head guided by a self-aligned and self-cleaning sliding carriage with spring system.
  • Resolutions up to 1 μm and repeatability ± 1 increment.
  • Accuracy grade ± 15 μm.
  • Measuring length up to 30,000 mm in modular version.
  • Profibus-DP, Profinet, CANopen, DeviceNet, ModBus and DRIVE-CLiQ protocols, through conversion gateways.
  • Sealing lips for the protection of the magnetic band, made of special elastomer resistant to oil and wearing.
  • Various possibilities of application, with double-effect joint or steel wire. An adapter guarantees the compatibility with PBS-HR scale.
  • High stability and quality of signals even in case of high speed, strong accelerations and vibrations.
  • Protected against inversion of power supply polarity and short circuits on output ports.
