Absolute Precision with Nonius Magnet Rings
In the evolving field of robotics, precision and reliability are paramount. Nonius magnet rings offer unrivaled benefits for an absolute measure of angle or position. Building on our experience in the development and manufacturing of magnet rings for the automotive market, we have refined our expertise in providing high-performance magnetic measurement solutions for all industries.
Our team of magnetization experts and our production facilities enable us to offer a wide range of Nonius magnetic rings for demanding positioning, rotation, and motion applications.
The properties of rubber, combined with our know-how of rubber-to-metal bonding, guarantee excellent performance even in extreme environments. Combined with iC-MU series Hall-effect sensors, magnet rings create absolute measurement systems.

Our Nonius magnet rings offer:
• High precision in position detection, making them ideal for applications requiring high levels of control and feedback.
• Robust performance even in harsh conditions, ensuring consistent operation and reducing maintenance needs.
Our solutions improve the accuracy of robotic movements, enabling more complex and precise tasks to be performed. Their integration into systems enhances the capabilities and performance of robots, driving forward the future of automation and intelligent machines such as exoskeletons.
Ensuring Longevity with Sealing Solutions
It is also essential to guarantee the longevity and reliability of components. Rubber sealing solutions offer a robust barrier against environmental factors. As a leading manufacturer of sealing technologies, we design solutions to prevent the ingress of dust, moisture, and other contaminants, protecting sensitive components and enhancing their operational lifespan.

Our rotating seals:
• Provide a high level of protection even in continuous motion.
• Ensure that the internal mechanisms of robots are not contaminated to keep operating smoothly. This is essential for maintaining the accuracy and efficiency of robotic systems, particularly for repetitive or high-speed tasks. We can also combine the sensing and sealing functions into a single product. In this way, the magnetized pack seal can be adapted to the tightest environment.
Our plate seals are bi-material rubber parts bonded to a rigid insert. Their robust design and high-performance materials ensure that they can withstand extreme environments.
By integrating sensing and sealing solutions, robotic systems can achieve greater reliability, reduce maintenance needs, and enhance overall performance. Our solutions provide essential accuracy and protection, ensuring that robotic components operate efficiently and reliably, even in the most challenging conditions.
