The crimp ferrule and centre contact are sized to the 0.212-inch nominal dielectric diameter of RG-59 class cable. If your BOM calls out RG-58, 58A, 58C, 141, or LMR-195, the sibling 31-320-RFX uses the same body and gold-plated contact but with a ferrule and centre pin sized for the smaller RG-58 dielectric. Same 50 Ohm impedance, same 4 GHz ceiling, same 500-cycle bayonet — the only difference is the cable group the kit fits.","metaTitle":"Amphenol 031-321-1012 BNC Plug, 50 Ohm, 4 GHz, RG-59","metaDescription":"Amphenol 031-321-1012 BNC plug, male pin, 50 Ohm impedance, 4 GHz max frequency, crimp termination for RG-59 double braid cable. 500 mating cycles, -65 to","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":"-","Package":"Bulk","Features":"-","Includes":"3 pcs - 1 Connector, 1 Contact, 1 Ferrule","Impedance":"50Ohm","Body Finish":"Nickel","Cable Group":"RG-59 Double Braid, Belden 9231","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Plug, Male Pin","Fastening Type":"Bayonet Lock","Insertion Loss":"0.2dB","Product Status":"Active","Voltage Rating":"500 V","Connector Style":"BNC","Frequency - Max":"4 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Crimp","Base Product Number":"031-32","Contact Termination":"Crimp","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C~165°C","Center Contact Plating":"Gold","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.1900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b63e358642991376227b2b335beb2bd2.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/031-321-1012/alternatives.json"},"ai":{"faq":[{"question":"What is the impedance of 031-321-1012?","answer":"The 031-321-1012 is a 50 Ohm BNC plug, matched to standard 50 Ohm coax systems for video, RF instrumentation, and telecom signal paths."},{"question":"Is 031-321-1012 compatible with RG59 double braid cable?","answer":"Yes, the 031-321-1012 is specifically listed for RG-59 double braid and Belden 9231.
