Sealed linear encoders

Sealed linear encoders from HEIDENHAIN are protected from dust, chips and splash fluids and are ideal for operation on machine tools.

  • Accuracy grades as fine as ± 2 μm
  • Measuring steps as fine as 0.001 μm
  • Measuring lengths up to 30 m (to 72 m upon request)
  • Fast and simple installation
  • Large mounting tolerances
  • High acceleration loading
  • Protection against contamination

Sealed linear encoders are available with

  • Full-size scale housing
    – For high vibration loading
    – Up to 30 m measuring length
  • Slimline scale housing
    – For limited installation space
    – Up to 1 240 mm measuring length, up to 2 040 mm with mounting spar or tensioning elements

The aluminum housing of a HEIDENHAIN sealed linear encoder protects the scale, scanning carriage, and its guideway from chips, dust, and fluids. Downward-oriented elastic lips seal the housing. The scanning carriage travels along the scale on a lowfriction guide. It is connected to the external mounting block by a coupling that compensates unavoidable misalignment between the scale and the machine guideways.
