Adding to its family of model LCs, Heidenhain Corporation now offers the absolute sealed LC 182 linear scale, which covers measuring lengths as large as 167" (4,240 mm).
The requirement for long absolute measurement has traditionally been met by incremental scales featuring distance-coded reference marks, according to the company. With this new system, virtually all kinds of dynamic extended travel applications—even linear motors and high speed machine tools—can be accommodated.
In this encoder, the company has included its single-field scanning method (versus a previous four-field scanning method) into the design. This incorporates a large single scanning window, thereby mitigating effects of contamination. In addition, high traversing speeds and increased natural frequency are said to result.
The product also offers continuous signal quality over the entire measuring length, with resolution to 0.02 micron and traversing speeds as high as 120 m/min.
