Main features & Overview

Visión general

Contactless absolute linear position transducer with ONDA magnetostrictive technology.

The Profibus fieldbus interface integrates in complex systems with long communication distances, guaranteeing rapid and secure data transmission.

The absence of contact on the cursor eliminates all wear and ensures almost unlimited life of the transducer.

Its many advantages include smaller size for easier installation, high protection rating for use in harsh environments, excellent linearity, repeatability, and resistance to vibration and shock, guaranteeing exceptional reliability.
