It is built for the RF engineer who needs a clean, repeatable interconnect at the panel face — the impedance is 50 Ohm, not 75 Ohm, so it belongs in a 50-ohm system (test gear, radio equipment, telecom infrastructure) and will cause a mismatch in a 75-ohm video path. ## 4 GHz ceiling, 10000-cycle floor Rated to 4 GHz, this adapter covers the full BNC practical band — VHF/UHF, ISM, cellular backhaul up to L-band, and most lab instrumentation. The 10000 mating cycles tell you the interface is built for frequent connect/disconnect duty: patch panels, test jigs, or field-deployed equipment where the cable gets swapped regularly. Silver plating on the centre contact and body (beryllium copper centre pin, brass shell) keeps contact resistance low and resists corrosion over those cycles. ## Flange-mount bulkhead fit Panel mount with a flange — the adapter bolts to the outside of an enclosure, presenting two BNC jacks: one inside for the internal cable, one outside for the field run. The straight body keeps the signal path axial; no right-angle bend to introduce a parasitic reactance. The PTFE dielectric maintains consistent impedance through the barrel.","metaTitle":"Hirose BNC-PA-JJ(40) BNC Jack-to-Jack Adapter, 50 Ohm, 4 GHz","metaDescription":"Hirose BNC-PA-JJ(40) BNC jack-to-jack adapter, 50 Ohm impedance, 4 GHz max frequency, 10000 mating cycles, silver-plated brass body, panel mount with flange.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Hirose Electric Co Ltd","Style":"Straight","Series":"BNC","Package":"Bulk","Features":"-","Includes":"-","Impedance":"50Ohm","Body Finish":"Silver","Adapter Type":"Jack to Jack","Body Material":"Brass","Center Gender":"Female to Female","Mating Cycles":"10000","Mounting Type":"Panel Mount","Adapter Series":"BNC to BNC","Fastening Type":"Bayonet Lock, Bayonet Lock","Insertion Loss":"-","Product Status":"Active","Conversion Type":"Same Series","Frequency - Max":"4 GHz","lifecycle_stage":"unknown","Mounting Feature":"Flange","Ingress Protection":"-","Base Product Number":"BNC","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-","Center Contact Plating":"Silver","Center Contact Material":"Beryllium Copper","Convert To (Adapter End)":"BNC Jack, Female Socket","Convert From (Adapter End)":"BNC Jack, Female Socket"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$30.6400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/99bf75fea6c1434773261f53de8d9b9d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum frequency of BNC-PA-JJ(40)?","answer":"The adapter is rated to 4 GHz maximum frequency, covering the full practical BNC band for RF test and telecom applications."},{"question":"How many mating cycles does BNC-PA-JJ(40) support?","answer":"The BNC-PA-JJ(40) is rated for 10000 mating cycles, making it suitable for frequent connect/disconnect environments like patch panels and test equipment."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/hirose-electric-co-ltd/BNC-PA-JJ~140~2","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/BNC-PA-JJ~140~2 when reusing this data.
