Tap into our cutting-edge connectivity technologies

To design your unique custom connector, you can tap into our cutting-edge technologies used for high-performance connectivity in extreme environments. Our expertise in sealing, high density, ruggedness and high-speed data transmission is renowned worldwide:

  • Built and assembled with robust materials and a rugged design to endure the toughest conditions: extreme temperatures, vibrations and shocks, corrosion, chemicals, radiations


  • Waterproofness / IP68 sealing for underwater applications  – resin-sealed contact blocks, IP68-sealed even unmated, deeper than -20m/24h upon request


  • Hermeticity and IP69K sealing for gas tightness in vacuum applications or pressurized vessels


  • Miniaturization for portable, handheld or body-worn applications with optimal SWaP (size, weight and power) for reducing the overall dimensions and weight of your device while increasing its efficiency and lowering the overall footprint


  • Multiprotocol high-speed data transfer for data-heavy applications – 18 Gbit/s with HDMI 2.0, 10 Gbit/s with USB 3.2. Gen 2 and Ethernet, Single Pair Ethernet


  • Hybrid/mixed combination of power, data, fluidic and optical contacts into a single cable/connector

Our connectors are developped in compliance with industry standards such as MIL SPEC and IEC 60601-1 for Means of Patient Protection (MOPP) and Means of Operator Protection (MOOP).

Our dedicated team of engineers are available worldwide


We understand that customization is extremely important to our customers. That’s why we have a team of experienced local field-application engineers and solution architects who are dedicated to working with you to create the perfect solution for your needs.
