Solving connector reliability issues in high-vibration environments
When an aircraft is in flight, pilots and passengers trust it will safely operate without fail. Aircraft manufacturers trust IEH
Jan 23, 2025
Project Overview
After failed attempts with a previous supplier of standard connectors, a manufacturer of Full Au-thority Digital Engine Control (FADEC) systems – autonomous, computerized aircraft engine control units – partnered with IEH Corporation to engineer Hyperboloid Contacts and Connectors that could provide uninterrupted signal transmission, even in the most demanding conditions, such as rapid altitude changes and speeds exceeding 600 mph.
CHALLENGE
Standard connectors were failing early in testing, jeopardizing costs, timelines, and safety in critical FADEC systems. To address this, manufacturers required Hyperboloid Contacts and Connectors capable of passing rigorous testing, enduring continuous stress, and ensuring longterm reliability.
THE SOLUTION
IEH’s Hyperboloid Contacts and Connectors provided secure, reliable signal integrity under extreme vibration and stress, replacing standard connectors to prevent costly delays and repairs, saving tens of millions.

IEH’s Hyperboloid Contacts and Connectors provided secure, reliable signal integrity under extreme vibration and stress, replacing standard connectors to prevent costly delays.
THE PROCESS
From the initial consultation, IEH closely collaborated with the customers’ engineering teams to meet specific project requirements. The project quickly progressed, a much- needed pivot after the failures of the previous connectors.
- Timeline Follow-Through: With IEH, the project began immediately to minimize further delays and costs. The project was executed hitting all milestones in a timely manner.
- Overcoming Obstacles: With extensive testing, IEH achieved reliable connectivity.
- Innovative Approach: IEH retrofitted its Hyperboloid Connectors to integrate seamlessly into the existing FADEC systems, eliminating the need for costly overhauls of
THE RESULTS
A partnership with IEH proved to be essential for these FADEC systems manufacturers: with the ability to weather extreme aerospace conditions, IEH’s Hyperboloid Contacts and Connectors enabled more consistent engine performance and reduced downtime for maintenance. IEH continues to deliver tailored, high-performance solutions that meet mission-critical demands while providing long-term value and reliability.
