Description
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 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.
The linear encoders with slimline scale housing (70mm-1240mm) are designed for limited installation space. Larger measuring lengths and higher acceleration loads are possible through the use of a mounting spar or clamping elements (up to 2040mm).
