USB-C Connector For Tough Use

The USB-C connector made for harsh use stays locked during shock and vibration and transfers data safely in places like factories, vehicles, and machines.

Fischer Connectors has adapted the universal USB-C standard for harsh environments. The company’s UltiMate Series now includes a pre-cabled USB-C connector featuring the new Ratchet Locking System (RLS). This connector delivers strong resistance to vibration and shock, making it suitable for high-speed data transfer in tough sectors like defense, mining, construction, motorsports, and railways.

The UltiMate USB-C with RLS combines fast data transmission with proven mechanical reliability. It’s designed for mission-critical applications—such as armored vehicles, UAVs, UGVs, and heavy machinery—where high vibration and shock are common.

At the core of this design is the Ratchet Locking System (RLS), which uses an asymmetrical tooth profile to stay securely locked under load and prevent loosening during high vibration. It offers key advantages such as high vibration resistance, tool-free operation even when wearing gloves, and a long lifespan with thousands of mating cycles. Integrated into the size 15 UltiMate housing—supporting up to 27 pins—the RLS delivers top performance within Fischer’s product range, withstanding up to 37.8 Grms of random vibration and 300 g of shock.

“Our new USB-C RLS connector offers environmental and mechanical performance in compliance with IEC and MIL-STD norms,” says Alexandra Monchâtre, Head of Product Management at Fischer Connectors. “This new product truly offers the best of both worlds: the ultra-standard and the ultra-rugged.”

“As part of our technology and innovation strategy, our Group R&D team offers engineers designing applications in extreme environments a versatile technology platform with various standards and connector types,” explains Alvaro Goncalves, Technology Director at the Conextivity Group, of which Fischer Connectors is a part. “This new USB-C connector with RLS is a good example of how we combine our technology ‘bricks’ – high-density miniaturization, high-speed data, and ruggedness – to increase integration capability, compatibility, and interoperability across customer markets. Conextivity has the innovation, agility, and precision skills needed to meet the most stringent requirements in demanding environments.”
