The 50 Ohm impedance holds through 6 GHz, with a PTFE dielectric keeping the phase stable across the band. Gold plating on the beryllium copper center contact resists corrosion over 500 mating cycles; the threaded coupling nut delivers a vibration-resistant mate that holds torque in outdoor enclosures. ## Sealing and Environment Rated IP67, this jack seals dust-tight and survives immersion when mated with the corresponding TNC plug. Designed specifically for LMR-240 cable. The crimp ferrule compresses over the jacket and braid; the center contact solders to the center conductor.","metaTitle":"031-6921 TNC Jack, IP67, 50 Ohm, 6 GHz, LMR-240","metaDescription":"031-6921 TNC jack, female socket, IP67 bulkhead mount for LMR-240 cable. 50 Ohm, 6 GHz max, 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":"Amphenol RF","Series":"TNC","Package":"Bag","Features":"-","Includes":"-","Impedance":"50Ohm","Body Finish":"Nickel","Cable Group":"LMR-240","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Panel Mount","Connector Type":"Jack, Female Socket","Fastening Type":"Threaded","Insertion Loss":"-","Product Status":"Active","Connector Style":"TNC","Frequency - Max":"6 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Bulkhead - Front Side Nut","Ingress Protection":"IP67 - Dust Tight, Waterproof","Shield Termination":"Crimp","Base Product Number":"031-69","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C~165°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.3300","stockQuantity":16,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/555fee758bd55702e5199a72a1e372e8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the 031-6921 compatible with LMR-240 cable?","answer":"Yes, the 031-6921 is specifically designed for LMR-240 cable group, with the crimp ferrule and center contact sized for that cable's dielectric and braid."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/031-6921","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/031-6921 when reusing this data.
