According to the company, 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 0.005 μm
  • Measuring lengths up to 30 m
  • 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 1240 mm measuring length, up to 2040 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 low-friction guide. It is connected to the external mounting lock by a coupling that compensates unavoidable misalignment between the scale and the machine guideways.

Notes From Heidenhain About Sealed Linear Encoders

According to the company, linear encoders with full-size scale housing (sealed) are characterized particularly by high tolerance to vibration.  Absolute linear encoders of the LC 100 and LC 200 series provide the absolute position value without any previous traverse required. Depending on the version, incremental signals can be output additionally.

The LC 100 can be mounted to the same mating dimensions as the incremental linear encoders of the LS 100 series and feature the same mechanical design. Because of their high accuracy and defined thermal behavior, LC 100 and LS 100 series linear encoders are especially well suited for use on numerically controlled machine tools.

The incremental encoders of the LF type feature measuring standards with relatively fine grating periods. This makes them particularly attractive for applications requiring very high repeatability. The LS 600 series incremental linear encoders are used for simple positioning tasks, for example on manual machine tools.

The LC 200 (absolute) and LB (incremental) linear encoders were conceived for very long measuring lengths up to 30 meters. Their measuring standard—a steel tape with METALLUR or AURODUR graduation— is delivered as a single piece, and after the housing sections have been mounted, is pulled into the housing, drawn to a defined tension and fixed at both ends to the machine casting.
