The Stac64 stackable connection system from Molex is now validated against the most stringent specifications from major automotive OEMs in Germany, France and Japan. According to the company, it is the only connector manufacturer to surpass the requirements.Designed originally as a standard product system based on USCAR-2 Class II mechanical and electrical performance characteristics for unsealed connector applications, new patents have been granted relating to the stackable header. The stackable connectors allow OEMs to support both low-level signal requirements as well as power applications upwards of 30A. It also allows manufacturers to use header assemblies as standalone components or to gang multiple headers together to support a large range of signal and power needs for devices and modules.
