Linear Absolute Magnetic Encoder

LA11

Not recommended for new design. Please go to Artos™ DHL or Artos™ DBL linear absolute magnetic encoder systems.

LA11 is an absolute magnetic linear encoder system designed for motion control applications as a position and velocity control loop feedback element. The encoder system is highly reliable due to contactless absolute measuring principle, built-in safety algorithms and high quality materials/components used.

For applications which demand that the AS scale can be removed easily please consider TRS track system.
