Heidenhain: Sealed Linear Encoders

Heidenhain’s sealed linear encoders from are protected from dust, chips and splash fluids and are ideal for operation on machine tools. Its accuracy grades are as fine as ± 2 μm with measuring steps as fine as 0.001 μm. Installation is simple and fast with large mounting tolerances and high acceleration loading.

There is protection against contamination. The encoders are available with full-size scale housing for high vibration loading and up to 30 m measuring length.

They also come in Slimline scale housing for limited installation space. Aluminium housing protects the scale, scanning carriage, and its guideway from chips, dust, and fluids. The scanning carriage travels along the scale on a low-friction guide. It is connected to the external mounting block by a coupling that compensates unavoidable misalignment between the scale and the machine guideways.
