Built to Perform. Designed to Solve.

IEH produces the highest quality Hyperboloid connectors in a cost-effective structure. Combining superior performance, competitive solutions and creative engineering, IEH helps manufacturers meet any connectivity challenge with 80+ years of proven reliability.

Hyperboloid technology uses angled straight wires that flex to wrap around pins, creating multiple contact lines for unmatched reliability. This proven design delivers low insertion force, superior current-carrying capacity, immunity to shock and vibration, and 100,000+ mating cycles in the most demanding environments.

In use for over 40 years under the most demanding conditions, Hyperboloid technology has proven itself to be the leading design for integrity and reliability. On avionics platforms, military and commercial aerospace equipment, engine control systems, missiles and torpedoes, vehicular electronics, satellites and rocket launchers, medical devices, industrial and environmental controls, test equipment, PGA sockets and countless other rugged applications, Hyperboloid has lived up to its promise of the highest reliability connector available.

IEH Hyperboloid connectors exceed military and aerospace specifications with impervious shock and vibration resistance, improved current-carrying capacity, low contact resistance, extended cycle life, very low insertion force, and advanced engineering design for mission-critical applications.
