It is incredibly vital that signaling relays, used in train control systems, work under extreme conditions. A leading manufacturer of rail signaling systems was looking for a way to improve the reliability and long-term performance of several electromechanical relay components in order to improve the overall safety of rail traffic.
To function, these rail relays must have:
- Low “magnetic remanence”
- Resistance to aging
- Control of “stack tolerance”
Filling all of these demands for such a specific application proved to be impossible for other manufacturers.
