Linear Magnetic Scale Absolute (PRC - Pseudo Random Code) Linear Magnetic Scales (LMS) are the basis for highly accurate incremental and absolute magnetic measurement systems. The magnetization process, developed and patented by BOGEN, writes the magnetic poles with an exceeding accuracy referring to width and position. LMS is resistant against environmental influences like production residues, utilities, vibrations and other. The operating temperature ranges from - 40°C up to + 100 °C. Accuracy classes up to ± 3 μm ensure magnetic scale solutions for a great number of customer applications, such as automation technology, robotics, mechanical and electrical engineering. Incremental Measuring Linear Applications Counting Controlling Features and Benefits • highly accurate encoded pole pairs • different accuracy classes available • resistant to contamination, vibrations, temperature fluctuations, humidity LMSA rev 1.0 (2023/10/25) • no wear from usage • customized variants on demand
