SMA2 is an absolute magnetic linear encoder system designed for demanding motion control applications that require high precision and high operating speeds. The compact form factor and IP67 rating makes it ideal for space-constrained installations and harsh industrial environments where dust, debris, and vibrations are prevalent.

The non-contact operation is virtually wear-free and delivers unparalleled reliability in critical applications, minimizing downtime and maximizing productivity.

Key Features:

  • BiSS, SSI, Panasonic interface
  • IP67 protection - excellent immunity to dust, debris, liquids
  • High resistance to shocks and vibrations
  • Resolutions down to 1 µm
  • 10 m/s travel speed
  • Measurment length up to 8.1 m
  • Large mounting tolerances simplify installation
  • Additional track for speed feedback
  • Hi-flex cable rated for millions of cycles
