45140-000030

The 45140-000030 by 3M 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 0.050" (1.27mm) 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.0.050" (1.27mm) 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.Supporting 30 AWG automotive primary wire, the contacts maintain stable resistance through 1500 thermal cycles. The optimized crimp profile prevents strand breakage.The Feed Through include integrated shorting bars for safe airbag connector handling. These safety features prevent accidental deployment during vehicle maintenance.The Gold 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.
