From a single wire and cable company to a global leader in interconnect technologies, our story is one of transformation, resilience, and relentless innovation. Here's how we got here—and where we're headed next.
The Beginning: Tensolite and Carlisle Era
Our journey began in 1940 with the founding of Tensolite, a company focused on high-performance wire and cable solutions. In 1959, Tensolite became part of Carlisle Companies, marking the start of a long and fruitful partnership.
Over the next few decades, we expanded through strategic acquisitions like VEMCO, UniTrek, and CDI Connecting Devices, each one adding new capabilities and helping us build a diversified portfolio of interconnect solutions.
Rebranding and Global Expansion
In 2008, we rebranded as Carlisle Interconnect Technologies, a name that reflected our broader mission and growing influence across aerospace, defense, and medical sectors.
Between 2007 and 2016, we welcomed several companies into our fold, including:
- Yichang Qiatou Wire & Cable Assembly (China)
- Carlyle, ECS, JERRIK, and TRI-STAR Electronics International
- Thermax, Raydex, Star Aviation, and Micro-Coax
These additions strengthened our expertise in RF technology, aircraft systems, and precision connectors—positioning us as a trusted partner in high-stakes industries.
Innovation-Driven Growth
From 2018 to 2020, we focused on innovation and diversification. Acquisitions like Tenencia Aerospace Design, RedGroup, Providien, MicroConnex, and LION Precision expanded our reach into design engineering, microelectronics, and precision sensing.
This era marked a shift toward future-ready solutions, allowing us to meet the evolving needs of our customers with greater agility and technical depth.
A New Chapter: Joining Amphenol
In 2024, we entered a transformative phase by joining Amphenol Corporation, one of the world’s largest manufacturers of interconnect products. This strategic move aligned us with Amphenol’s global scale, resources, and innovation ecosystem.
By 2025, we proudly reintroduced ourselves as Amphenol CDI—a name that honors our legacy while embracing the future.
“Becoming ACDI represents the leadership organization of Amphenol, brand recognition, and a commitment to be ahead of the competition and a leader within our industry.”
— Tony Norris, Business Unit Director
What’s Next for Amphenol CDI?
As Amphenol CDI, we’re accelerating into the future. You’ll see continued enhancements across our operations, offerings, and customer experience. From updated branding and digital platforms to expanded global support, we’re committed to delivering even greater value.
“We’ll be able to do things that haven’t been done before. Personally, I’m passionate about developing a complete new set of younger talent engineers to carry on the legacy.”
— Tony Norris
This next chapter builds on a remarkable foundation of innovation. As Tony reflects:
“Eighty years ago, CDI began by designing RF connectors—some of the most popular on the market today. We are now embarking on a new journey with our parent Amphenol to design high-density RF interconnects, supporting a market need for more data from a smaller footprint.”
— Tony Norris
When asked to describe our future in one word, Tony chose:
“Innovation.”
“Because we are bringing new ways of supporting high-density RF connectivity.”
Celebrating the People Behind Progress
While our technology and growth tell one part of the story, it’s our people who truly define Amphenol CDI. Their dedication, adaptability, and expertise have been the driving force behind every milestone—from our early days as Tensolite to our transformation into a global leader.
As we continue evolving, we recognize that change is only possible because of the individuals who embrace it with resilience and purpose. To honor that spirit, we’re launching a new social media series: Inside ACDI.
This campaign will spotlight employees across departments and locations, sharing their experiences, insights, and reflections on what it means to be part of our journey. Through these stories, we aim to celebrate the culture, talent, and teamwork that make Amphenol CDI not just a company—but a community.
Stay tuned as we highlight the voices that have helped shape our past and build our future.
