66564-740LF

The 66564-740LF by Amphenol ICC (FCI) redefines reliability in Rectangular Connectors - Free Hanging, Panel Mount, developed for automotive electronics where vibration resistance is critical. This next-generation connector system delivers superior performance in engine control units, ADAS sensors, and in-vehicle networking applications, meeting stringent automotive qualification standards.As a Receptacle solution, it incorporates automotive-specific CPA (Connector Position Assurance) features. The secondary locking mechanism prevents accidental disconnection from vehicle vibrations.The Female Socket design utilizes a multi-finger contact system that compensates for terminal tolerance variations. This self-adjusting feature maintains stable electrical connection through thermal cycling.Available in 40 configurations, the connector supports both power distribution and high-speed data networks. The hybrid contact arrangement accommodates mixed signal types within a single housing.The 0.100" (2.54mm) spacing meets USCAR-2 vibration requirements while allowing sufficient creepage distance. This optimized layout prevents dust accumulation in under-hood applications.The 2 row design incorporates power contacts in the outer rows for better heat dissipation. This arrangement reduces thermal derating effects in high-current applications.0.100" (2.54mm) separation between rows prevents electromagnetic interference between power and signal circuits. This spacing is critical for CAN FD and automotive Ethernet signals.The Free Hanging (In-Line) version includes integrated sealing for IP6K9K protection. The molded sealing lips maintain environmental protection through repeated mating cycles.Featuring IDC technology, the system provides pull-out forces exceeding 50N per contact. The quadruple crimp wings ensure mechanical stability in high-vibration environments.Compatible with Ribbon Cable automotive-grade cables, the contacts meet GMW3191 salt spray requirements. The special contact geometry prevents fretting corrosion from micro-movements.The Feed Through, Polarizing Key include integrated shorting bars for safe airbag connector handling. These safety features prevent accidental deployment during vehicle maintenance.The Gold, GXT™ plating exceeds LV214 sulfur resistance tests. The nano-crystalline structure provides exceptional wear resistance against automotive mating cycles.With 30.0µin (0.76µm) plating, the contacts exceed 1000 mating cycles while maintaining contact resistance below 5m . The diffusion barrier layer prevents intermetallic growth.The Blue housing material passes BMW GS96024-5 heat aging tests. The laser-markable surface allows permanent identification without label degradation.
