linear encoder from HeidenhainSealed Linear Encoders

Sealed linear encoders from HEIDENHAIN are protected from dust, chips and splash fluids and are ideal for operation on machine tools. An aluminum housing and elastic sealing lips protect the scale, scanning carriage and guideway from chips, swarf, dirt and splash water The scanning carriage travels in a low-friction guide within the scale unit. It is connected to the external mounting block by a coupling that compensates unavoidable misalignment between the scale and the machine guideways.

Sealed linear encoders are available with full-size scale housings for high resistance to vibration up to 30 m measuring length, as well as slimline scale housing for limited installation space up to 2040 mm measuring length.

Fundamentals of Linear Encoders

Linear encoders from HEIDENHAIN can be used nearly everywhere. They are ideal for machines and other equipment whose feed axes are in a closed loop, such as milling machines, machining centres, boring machines, boring mills, and grinding machines.

Linear encoders measure the position of linear axes without additional mechanical transfer elements. This can eliminate a number of potential error sources.

The aluminium housing of a sealed linear encoder protects the scale, scanning carriage, and its guideway from chips, dust, and fluids. The scale is scanned photoelectrically and as such without mechanical contact or wear. HEIDENHAIN supplies both incremental and absolute linear encoders.

Slimline Housing

Linear encoders with slimline scale housing are designed for limited installation space. Larger measuring lengths and higher acceleration loads are made possible by using mounting spars or clamping elements.

Full-size Housing

Linear encoders with full-size scale housing are characterized by their sturdy construction, high resistance to vibration and large measuring lengths. The scanning carriage is connected with the mounting block over an oblique blade that permits mounting both in upright and reclining positions with the same protection rating.
