GVS 608

Absolute optical scale for CNC machine tools

  • Absolute optical scale with glass measuring support, particularly suitable for CNC machine tools.
  • Serial interface SSI-BiSS, with or without 1 Vpp analog signal, Siemens DRIVE-CLiQ and FANUC αi.
  • Resolutions up to 0.1 μm.
  • Accuracy grade up to ± 1 μm.
  • Profibus-DP, Profinet, CANopen, DeviceNet and ModBus protocols, through conversion gateways.
  • Non-extendible sealing lips, along the sliding side of the reader head, fixed at the lateral ends.
  • Innovative device inside the scale for the disposal of liquids coming from inefficient filtering systems.
  • The special sealing lips and the device for the liquids disposal provide an excellent protection of the grating
    from refrigerant liquids often used during machining.
  • Metrological certificate provided with each scale.
  • Linear thermal expansion coefficient λ = 8 x 10-6 °C-1.
  • High accuracy and stability of signals even in case of high speed, strong accelerations and vibrations.
  • Adjustable connecting cable output.
  • Connector inside the transducer.
  • Protected against inversion of power supply polarity and short circuits on output ports.
  • Small size, to allow installation in narrow spaces.
  • Interchangeable with the previous model AGS.
  • Filtering system for pressurization available on request.
