If the standard solutions offered by Exxelia cannot fulfill customers' requirements, Exxelia can develop custom designs to ensure customers' can use the potentiometers without having to adapt their design. Customization can range from very simple modifications such as :

  • mechanical interface,
  • solid or hollow shaft option,
  • bearingless,
  • extended temperature range (very low or very high),
  • water (or any liquid) proof,
  • vaccum compatibility,
  • ...

 

Exxelia also offers custom potentiometers to respond to all mechanical, thermal, and environmental demands, ensuring they perform in the most extreme conditions including under vacuum.

Exxelia’s potentiometers are widely used in space applications such as satellites (solar array drive mechanisms, pointing systems), space exploration rovers, and critical space instruments. With our expertise in space-qualified potentiometers, we provide tailored solutions that meet the rigorous standards of the space industry. Our potentiometers come in all sizes, from miniature to large-scale, with RoHS-compliant options

Exxelia’s custom designs and bearingless sensor solutions are ideal for space missions where reliability and precision are paramount.


With decades of experience in high reliability potentiometers (including space-grade potentiomètres), Exxelia is the go-to partner for aerospace companies and space agencies looking for advanced, reliable potentiometer solutions for their space missions.
