It is a same-series conversion adapter, meaning it joins two HD-EFI plugs without changing the connector family. The beryllium copper body and center contacts, gold-plated on the mating surfaces, give it the mechanical cycle life and corrosion resistance for field-deployed and lab environments alike. The 6 GHz maximum frequency covers L-band through C-band applications; above that the insertion loss and VSWR rise beyond the adapter's design window. The straight body style keeps the cable run in line with the adapter axis, which simplifies routing in tight enclosures compared to a right-angle body. Free-hanging (in-line) mounting means no panel flange or bulkhead thread — the adapter floats in the cable run, secured only by the snap-on fastening at each end. ## Materials and Durability for the Deployment Both the body and center contacts are beryllium copper, chosen for its spring properties and conductivity over repeated mating cycles. The center contacts are gold-plated, which resists oxidation and maintains low contact resistance across the rated 200 mating cycles. The white bronze body finish provides a corrosion barrier without the galvanic compatibility issues nickel can introduce with stainless steel mating hardware.","metaTitle":"Amphenol RF 920-505A-51S HD-EFI Adapter, 50 Ohm, 6 GHz","metaDescription":"Amphenol RF 920-505A-51S HD-EFI straight plug-to-plug adapter, 50 Ohm impedance, 6 GHz max frequency.","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":"$8.2200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/fc02c7fed88e80373fa37e95b0400868.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/920-505A-51S/alternatives.json"},"ai":{"faq":[{"question":"Is the 920-505A-51S compatible with standard HD-EFI connectors?","answer":"Yes — this is a same-series adapter (EFI, HD to EFI, HD), so both ends mate with any standard HD-EFI plug connector.
