The cable group covers RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907 — match the body to the reel before you cut the cable. The 031-6166 is designed for the RG-58 family and its equivalents (LMR-195, Belden 9907). The shield termination is crimp — use the correct die for the ferrule, or the impedance step at the crimp will show up on the VNA. This jack mounts through a bulkhead panel and secures with a front-side nut, with the included gasket and lockwasher providing a weatherproof seal. The gold-on-phosphor-bronze center contact handles repeated reconnects without fretting, which matters for field-service gear that gets swapped out. ## RF Performance The 500 V voltage rating covers typical RF power levels on these cables. The weatherproof rating means it can live on an antenna or an outdoor enclosure without a secondary boot.","metaTitle":"031-6166 TNC Jack, 50 Ohm, 11 GHz, Bulkhead, Crimp","metaDescription":"Amphenol 031-6166 TNC jack, 50 Ohm, 11 GHz, bulkhead front-side nut mount, crimp termination, RG-58 cable group, gold center contact, 500 mating cycles","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Amphenol RF","Series":"-","Package":"Bulk","Features":"-","Includes":"6 pcs - 1 Connector, 1 Contact, 1 Ferrule, 1 Gasket, 1 Lockwasher, 1 Nut","Impedance":"50Ohm","Body Finish":"Nickel","Cable Group":"RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, 9907","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Panel Mount","Connector Type":"Jack, Female Socket","Fastening Type":"Threaded","Insertion Loss":"0.18dB","Product Status":"Active","Voltage Rating":"500 V","Connector Style":"TNC","Frequency - Max":"11 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Bulkhead - Front Side Nut","Ingress Protection":"Weatherproof","Shield Termination":"Crimp","Base Product Number":"031-61","Contact Termination":"Crimp","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C~165°C","Center Contact Plating":"Gold","Center Contact Material":"Phosphor Bronze"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.4286","stockQuantity":17,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/bed889122aea2915e5bc0387d1644b6b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the 031-6166 impedance and cable compatibility?","answer":"The 031-6166 is a 50 Ohm TNC jack rated to 11 GHz.
