    Linear Encoders for Numerically Controlled Machine Tools

    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.
