Ex-proof incremental encoders, shaft size up to 25 mm

With their robust construction and inductive scanning, these encoders work well also when subjected to vibrations, moisture, salt water, dirt, warm or cold temperatures, or shock from strong mechanical forces.

Our Ex-proof encoders are certified for use in hazardous areas, zones 1, 2, 21 and 22, where an explosive environment may occur. Ex certifications included in our product range:

  • ATEX (Europe)
  • EAC Ex (Russia and Eurasian economic union)
