System3d - optimal solutions for machine tools

Measurement of length 

Closed Heidenhain linear scales are protected from dust, chips and liquids. An ideal solution for use on machine tools. 

Open Heidenhain linear scales operate without mechanical contact of the head of the scale or measuring tape. A typical area of application of these devices include measuring machines, comparators and other precision instruments used in metrology linear motion, applications and production measurement, for example in the semiconductor industry. 

In the case of linear incremental measurement, the current position is determined by counting measuring steps, starting from the base point or by division and counting signal periods. The HEIDENHAIN incremental scales of incremental scales solution allowing the base point to be determined and reference marks scanned after switching on the machine. This process is particularly simple and quick as a result of the use of reference marks with coded distances. 

Absolute Heidenhain linear scales make it possible to determine the current position without movement. Information about the absolute position is transmitted from the ruler through the EnDat interface or another serial interface.

Closed Heidenhain linear scales: 

  • Accuracy up to ± 2 microns
  • Step measurement of up to 0.001 microns
  • measuring lengths up to 30 m (72 m on request)
  • Simple and quick installation
  • Large Installation tolerances
  • Ability to work with large accelerations
  • Protection against pollution
  • Sealed Heidenhain linear scales are available in the following versions:


With multi-profile body With a little profiled body 
  • Applications that require high resistance to vibration
  • Measuring length up to 30 m.
  • Applications with limited mounting space.
  • Measuring length up to 1 240 mm with the mounting rail or clamping elements to 2 040 mm.

The aluminum body of the closed HEIDENHAIN linear encoders protects the scale measuring element scanning the head and its guide from dust, chips, particles and splashing liquids. Flexible sealing lips close the body from the bottom. The head is moved along the scale on the measuring slide with low friction. The element scanning the head is connected to an outer mount by a flexible linker which compensates the deviation between the nominal position and scale ruler guides of the machine tool. 

Open Heidenhain linear scales 

Open Heidenhain linear scales are dedicated for use in machines and systems, which require high accuracy of the measured value. Typical application areas include:

  • production equipment and measurement equipment in the semiconductor industry
  • machines for PCB assembly
  • ultra-precision machine
  • machines with high accuracy
  • comparators and measuring machines, microscopes and other measuring devices
  • precise measuring instrumentsd
  • direct drives
