557691-4

The 557691-4 by TE Connectivity AMP Connectors revolutionizes Keystone - Faceplates, Frames applications in transportation systems, engineered to withstand the rigorous demands of mobile environments. Its vibration-resistant design and exceptional durability make it the preferred choice for rail and vehicular networking applications.The Single Gang configuration incorporates military-spec retention clips that maintain connection integrity under 5G vibration profiles. This advanced design exceeds EN 50155 standards for railway applications.As a Faceplate, this solution features hermaphroditic contacts that eliminate gender-specific failure points. The self-cleaning contact design maintains low insertion loss through 10,000 mating cycles in dusty conditions.With 6 ports, the layout supports redundant network architectures required in transportation systems. The configuration allows for both star and daisy-chain topologies within the same footprint.The Straight orientation was optimized for serviceability in confined equipment bays. This ergonomic design reduces maintenance time by 40% compared to traditional layouts.The Gray housing utilizes luminescent additives for low-light identification. This safety-enhanced feature meets ISO 3864 standards for emergency equipment visibility.Including Label Cover/Holder with Labels, Mounting Hardware, the design addresses unique mobile environment challenges. The integrated strain relief system prevents cable fatigue in continuous vibration scenarios.Compatible with 110 Connect, SL Series, MT-RJ Series, it forms the backbone of vehicle communication networks. The solution is qualified for use in both 12V and 24V electrical systems.The 4.500" (114.30mm) dimension reflects optimization for standard DIN rail mounting in vehicle cabinets. This space-efficient design maximizes equipment density in rolling stock applications.2.752" (69.90mm) width specification ensures proper airflow around heat-generating components. The design incorporates thermal breaks that prevent cold bridging in extreme temperature environments.With 0.591" (15.00mm) depth, the profile accommodates shock-mounted connectors without protruding. This streamlined design prevents snagging during equipment servicing.Constructed from Acrylonitrile Butadiene Styrene (ABS), the housing demonstrates exceptional resistance to fuels and hydraulic fluids. Material testing confirms operation across -55 C to 125 C without embrittlement.
