The threaded fastening and flange mount keep the connection stable under vibration, while the compression termination eliminates soldering variability at the board interface. ## 40 GHz vs Standard SMA — What Changes A standard SMA connector is specified to 18 GHz; beyond that, mode propagation and air-gap tolerances degrade the signal. The 2.92mm interface (also called K connector) uses a 2.92 mm outer conductor diameter and an air dielectric that supports a clean TEM mode up to 40 GHz. The HK-R-SR2-1 shares the same 1/4-36 thread as SMA, so it mates physically with SMA jacks, but the bead geometry and launch are tuned for 40 GHz — an SMA jack will limit the system to 18 GHz regardless of what is on the other side.","metaTitle":"Hirose HK-R-SR2-1 2.92mm Receptacle, 50 Ohm, 40 GHz","metaDescription":"Hirose HK-R-SR2-1 2.92mm receptacle, female socket, 50 Ohm impedance, 40 GHz max frequency, 500 mating cycles, gold-plated beryllium copper contact.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors","RF Cable Assemblies"],"specifications":{"Mfr":"Hirose Electric Co Ltd","Series":"2.92mm","Package":"Bulk","Features":"-","Includes":"-","Impedance":"50 Ohms","Body Finish":"-","Cable Group":"-","Body Material":"Stainless Steel","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Surface Mount","Connector Type":"Receptacle, Female Socket","Fastening Type":"Threaded","Insertion Loss":"-","Product Status":"Active","Connector Style":"2.92mm","Frequency - Max":"40 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Flange","Ingress Protection":"-","Shield Termination":"Screw","Base Product Number":"HK-R-SR2","Contact Termination":"Compression","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-55°C ~ 105°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$20.1800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/e3819e512421c76d198bac2f7c62f25f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is HK-R-SR2-1 suitable for 40 GHz applications?","answer":"Yes, the HK-R-SR2-1 is rated to 40 GHz maximum frequency with a 50 Ohm impedance, making it suitable for millimeter-wave test, radar, and high-speed data systems."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/hirose-electric-co-ltd/HK-R-SR2-1","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/hirose-electric-co-ltd/HK-R-SR2-1 when reusing this data.
