Absolute glass scale / from 70 mm to 3'240 mm / press brakes / ± 1 µm

GVS 204

Self-aligning optical absolute scale, with glass grid

  • Optically absolute length measuring system with glass scale. Especially suitable for applications on synchronized press brakes.
  • Serial interface SSI-BiSS, with or without 1 Vpp analog signal.
  • Reading head guided by self-aligned guide and self-cleaning carriage with spring system.
  • Resolution up to 0.1 µm.
  • Accuracy class ± 2.5 µm in the standard version and ± 1 µm in the high-precision version.
  • SSI protocol and programmable resolutions.
  • Profibus-DP, Profinet, CANopen, DeviceNet, Modbus and DRIVE-CLiQ protocols through conversion gateways.
  • The metrological certificate is provided with each length measuring system.
  • Oil-resistant elastomer sealing lips to protect against scratching.
  • High stability and quality of signals even at high speed and strong accelerations and vibrations.
  • Protection against polarity reversal of the power supply and short circuits on the output ports.
