Linear encoders for numerically controlled machine tools
Linear encoders from HEIDENHAIN for numerically controlled machine tools can be used nearly everywhere. They are ideal for machines and other equipment whose feed axes are in a servo loop, such as milling machines, machining centers, boring machines, lathes and grinding machines. The beneficial dynamic behavior of the linear encoders, their high permissible traversing speed, and their acceleration in the direction of measurement predestine them for use on highly-dynamic conventional axes as well as on direct drives.
Linear encoders with slimline scale housing
The 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.

Linear encoders with full-size scale housing
The 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.
