Field-proven robustness and performance

The vehicle of the future will face the same environmental challenges equal to or surpassing those of today – possibly even more severe. Our sealed IP6K7- and IP6K9K-rated products are specifically designed for harsh environments, such as temperatures ranging from -40° to +125°C and high vibration levels up to 25G with current ratings up to 21.0A.

Reliable, secure connections and mating

With any engine type, but especially with EVs and other next-generation vehicles, reliability is essential. The connector and terminal position assurance features provide extra assurance for a reliable connection. The CMC/CMX product family was also designed to meet strict mating force requirements. The lever and polarization features prevent mis-mating, reduce operator fatigue and make assembly easier.
