Heidenhain Acquires AMO

This deal expands their overall equipment portfolio of motion control systems.


Dr. Johannes Heidenhain GmbH (Traunreut, Germany) recently acquired AMO (St. Peter am Hart, Austria), a specialty encoder company that is well known for meeting the precision feedback requirements in applications where high resolution is needed, particularly in highly contaminated machine environments, such as in automation, medical and semiconductor work, as well as some metal forming, bending, and manual machine tool applications. As part of this acquisition, AMO sales operations and products are now coordinated at Heidenhain Corporation (Schaumburg, IL) in the U.S. for North America, while AMO encoder production and engineering remain in Austria.

AMO encoders are inductive based and can survive many types of rough environments, including coolants, slurries, heavy dust particles, high vibration and still maintain accuracy and high resolution. Both linear and angular encoders are available in many lengths and diameters. The linear encoders come in an exposed kit style or bearing-guided versions. The angular encoders are produced with either a thin tape with no joining seam or a drum type where both allow for easy installation onto various sized shafts. These encoders are available in absolute versions with Biss C, Fanuc, Mitsubishi, Yaskawa, and EnDat interfaces, and incremental versions with 1 Vpp and TTL.
