The LMSA (Linear Magnetic Scale Absolute) utilizes a patented magnetization process for precise magnetic pole writing, ensuring high accuracy and resistance to environmental influences. It operates within a temperature range of -40°C to +100°C and offers accuracy classes up to ±3 μm, suitable for applications in automation, robotics, and engineering.
Standard and optional layer stackups are available, with magnetic scales supplied in pieces or on reels. Optional accessories include extruded aluminum profiles, scale applicators, and clamps for scale ends.
Marking includes accuracy class, absolute code, year/week, and reel number. The order code specifies track parameters, length, width, height, accuracy class, cover tape, adhesive tape, text imprint, and mounting holes.
Examples provided for ordering include specifications for track parameters, accuracy class, dimensions, and additional features like adhesive tape and text imprint.

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.
