Absolute optical scale with stainless steel grid for machine tools/CNC machines /Measurement length: from 640 mm up to 30'040 mm or more on request / ± 5 μm

GVS 908

• Absolute optical scale, available in one piece or in modular design for large machines (up to 30,040 mm measuring length or more on request).
• Application in various industries such as machine tools, vertical lathes, gantry machines, laser/plasma cutting machines, robotics, automation, etc.
  Stainless steel grid, integrated in the machine guide, for excellent accuracy at any temperature.
• SSI-BiSS C serial interface (unidirectional), with or without 1 Vpp analog signal, and FANUC α-αi. Direct reading of the absolute dimension.
• Resolutions down to 0.1 μm.
• Degree of accuracy ± 5 μm.
• Permanently connected modules, for a perfect seal against liquids and environmental contaminants that do not change over time.
• Adjustable cable output, through double plug.
• Large alignment tolerances.
  Pressurization from both sides of the scale and/or transducer.
• Measuring length: from 640 mm to 30040 mm, with steps of 200 mm / Modules length: 1200, 1400, 1600, 1800, 2000 mm
