It is a same-series inline adapter rated for 50 Ohm systems from DC to 6 GHz, with a snap-on fastening on both ends. The body is copper alloy with a White Bronze finish, and the center contacts are gold-plated copper alloy. The dielectric is polyoxymethylene (POM). It is designed for free-hanging (inline) cable-to-cable or cable-to-equipment connections where a straight gender-changer is needed. ## 6 GHz Bandwidth and 200-Cycle Mating Life The 6 GHz frequency ceiling covers L-band, S-band, and most of C-band — suitable for cellular backhaul, GPS, Wi-Fi, and test equipment up to 6 GHz. ## Same-Series Conversion, No Panel Mount Because both ends are HD-EFI plug interfaces with female sockets, this adapter acts as a gender changer or barrel — it does not change series or impedance. The snap-on fastening on both ends provides quick connect/disconnect without tools.","metaTitle":"Amphenol RF 920-509A-51S HD-EFI Adapter, 50 Ohm, 6 GHz","metaDescription":"Amphenol RF 920-509A-51S HD-EFI straight plug-to-plug adapter, 50 Ohm, DC to 6 GHz, gold center contacts, 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":"Copper Alloy","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":"Polyoxymethylene (POM)","Operating Temperature":"-40°C~85°C","Center Contact Plating":"Gold","Center Contact Material":"Copper Alloy","Convert To (Adapter End)":"EFI, HD Plug, Female Socket","Convert From (Adapter End)":"EFI, HD Plug, Female Socket"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.2900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/7c314874537998db4eef316ce697083e.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/920-509A-51S/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the 920-509A-51S available via RFQ confirmation?","answer":"The 920-509A-51S is available to order against an RFQ.

HD-EFI is a higher-density variant of the standard EFI series; the snap-on interface and 50 Ohm impedance are common, but verify the mechanical keying and pin depth with your mating connector before committing."},{"question":"What is the difference between HD-EFI and standard EFI?","answer":"HD-EFI is a higher-density version of the standard EFI interface, offering more contacts in the same shell size. The 920-509A-51S is specifically an HD-EFI to HD-EFI adapter, so it is not a direct cross to standard EFI without a series-changing adapter."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/920-509A-51S","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/amphenol/920-509A-51S when reusing this data.
