Our story goes back to 1940, when Henry Dudley Minich founded what was then known as Tensolite. It consisted of a team of six researchers in an old converted house in North Tarrytown, New York. They started out investigating the properties and commercial possibilities of various plastics and synthetic fibers and eventually began to build a reputation for producing the finest miniature insulated wire and cable in the industry. Tensolite was an early pioneer in the application of insulation to miniature wire and was one of the first to apply a unique material called PTFE to produce high-temperature wire and cable. In fact, the company’s first insulated wire product was used to electrically heat the gloves and flight suits of World War II Air Force pilots.


In 1959, Tensolite became part of Carlisle Companies, setting the stage for a legacy of innovation. By 1998, the need for comprehensive interconnect solutions became apparent, leading to the birth of Amphenol CIT. A journey of expansion and acquisition began as CIT strategically added cable assemblies, RF/microwave and fiber optic solutions, structures, SATCOM solutions, and custom engineering to its portfolio. This transformation solidified CIT as a trusted end-to-end partner across the aerospace, military, space, T&M, med tech, and industrial markets.

Today & Tomorrow

Now, as we begin our latest chapter as Amphenol CIT (Cable & Interconnect Technologies), it signifies far more than two titans joining forces. It’s a promise of progress, a commitment to excellence, and a testament to the power of human ingenuity. It’s a fusion of expertise and vision where boundaries dissolve and innovation thrives.

It’s revolutionary connectivity reimagined.
