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.
