Magcoder

Absolute magnetic linear encoder with a battery

  • Magcoder Overview: Magcoder is a magnetic absolute position linear encoder featuring a 2 mm single-track magnetic scale and a battery-buffered encoder head. It offers cost-effectiveness, easy assembly, and high resolution of 0.1 μm. Compatible with Japanese servo drives (RS485) and European controllers (BiSS-C), it provides an optimal solution for industrial linear motion systems.

  • Gear Scale Option for Enhanced Environmental Resistance: In harsh environments involving water, contaminants, or risks of magnetic scale demagnetization, a gear-type scale option can be selected. This significantly enhances environmental robustness, ensuring stable and reliable performance.

  • Summary: Magcoder is a linear encoder combining cost-efficiency, high performance, and environmental adaptability, supporting efficient operations across various industrial applications.
