It is a straight, panel-mount adapter with a flange for bulkhead or chassis installation. ## What the Construction Tells You The stainless steel body gives this adapter the mechanical stiffness to survive panel-mount torque and cable strain without distorting the center conductor alignment. PTFE dielectric keeps insertion loss stable from DC through the rated band — it doesn't cold-flow or absorb moisture the way some lower-cost dielectrics do. Beryllium copper contacts with gold plating are standard for RF adapters that need repeatable mating over hundreds of cycles; the gold prevents oxidation on the mating interface, and beryllium copper retains its spring force so the female center contacts keep good grip on the male pin after many connects. Both adapter ends use threaded fastening — SMA on the convert-from side, TNC on the convert-to side. The panel mount uses a flange with clearance holes for two screws; the adapter body passes through the panel cutout and the flange seats against the outside face. Hand-tight should seal it for most indoor environments, but if the panel sees vibration, a torque wrench on the SMA and TNC coupling nuts is worth the extra minute — a half-turn loose is a dropout on a sensitive receive line.","metaTitle":"TE Connectivity 1057841-1, SMA Jack to TNC Jack Adapter","metaDescription":"1057841-1 TE Connectivity between-series adapter, SMA jack to TNC jack, panel mount flange, gold-plated beryllium copper contacts.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Style":"Straight","Series":"-","Package":"Bulk","Features":"-","Includes":"-","Impedance":"-","Body Finish":"-","Adapter Type":"Jack to Jack","Body Material":"Stainless Steel","Center Gender":"Female to Female","Mating Cycles":"-","Mounting Type":"Panel Mount","Adapter Series":"OSM to OST","Fastening Type":"Threaded, Threaded","Insertion Loss":"-","Product Status":"Obsolete","Conversion Type":"Between Series","lifecycle_stage":"unknown","Mounting Feature":"Flange","Ingress Protection":"-","Base Product Number":"1057841","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper","Convert To (Adapter End)":"TNC Jack, Female Socket","Convert From (Adapter End)":"SMA Jack, Female Socket"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.6237","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/19dae8ef93ccbbe4853c19b1edcfdc1f.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/1057841-1","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/te-connectivity-amp-connectors/1057841-1 when reusing this data.
