IEH Corporation specializes in the design, development, and production of high-performance printed circuit board (PCB) connectors and bespoke interconnect solutions. These sophisticated components are marketed and sold to customers in both the United States and abroad, where they serve as essential elements within larger, completed product assemblies. The company engages with original equipment manufacturers (OEMs) directly for sales, and also utilizes authorized representatives and distributors to reach its target markets. These primarily include demanding sectors such as military, aerospace, medical, industrial, test equipment, space, and commercial electronics. Founded in 1941 and based in Brooklyn, New York, the organization was initially named Industrial Heat Treating Company, Inc. before rebranding as IEH Corporation in March 1989.
