It is a same-series adapter — plug to plug, female to female — so it effectively extends an HD-EFI cable run or couples two HD-EFI plugs without changing the connector family. The body is machined from beryllium copper with a white bronze finish, giving it good corrosion resistance and RF shielding. The 6 GHz max frequency covers L-band through C-band, including most Wi-Fi, cellular, and GPS bands. The 200 mating cycles are typical for a snap-on coupling; the beryllium copper center contacts with gold plating hold their spring force through that cycle count, so the connection doesn't go intermittent after a few dozen swaps in a test setup. The straight body keeps the RF path axis-aligned — no right-angle bend to introduce a VSWR bump. ## Construction and Environmental Reach Beryllium copper body and center contacts give this adapter mechanical spring memory and good conductivity. The white bronze finish on the body is a nickel-tin alloy that resists corrosion better than plain nickel — relevant if the adapter lives in a cabinet with humidity cycling. The PTFE dielectric holds stable electrical properties from -55°C to 125°C, which covers outdoor telecom cabinets, industrial enclosures near heat sources, and unheated storage. The snap-on fastening on both ends means no tools needed for mating, but the retention is positive — it won't vibrate loose in a cabinet with fans.","metaTitle":"Amphenol 920-506A-51S HD-EFI Adapter, 50 Ohm, 6 GHz","metaDescription":"Amphenol 920-506A-51S HD-EFI straight adapter, plug to plug, female to female. 50 Ohm impedance, 6 GHz max frequency, 200 mating cycles.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Amphenol RF","Style":"Straight","Series":"HD-EFI","Package":"Tray","Features":"-","Includes":"-","Impedance":"50Ohm","Body Finish":"White Bronze","Adapter Type":"Plug to Plug","Body Material":"Beryllium Copper","Center Gender":"Female to Female","Mating Cycles":"200","Mounting Type":"Free Hanging (In-Line)","Adapter Series":"EFI, HD to EFI, HD","Fastening Type":"Snap-On, Snap-On","Insertion Loss":"-","Product Status":"Active","Conversion Type":"Same Series","Frequency - Max":"6 GHz","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Base Product Number":"92050","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-55°C~125°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper","Convert To (Adapter End)":"EFI, HD Plug, Female Socket","Convert From (Adapter End)":"EFI, HD Plug, Female Socket"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.4600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/936e4e441b46535c252d8f40bb0a13c8.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/920-506A-51S/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between the 920-506A-51S and standard EFI adapters?","answer":"This adapter is from the HD-EFI series, not the standard EFI series.
