The right-angle orientation changes the cable exit by 90 degrees relative to the mating axis, which is the primary reason to select this over a straight adapter — it keeps the cable routed flat against a panel or inside a tight enclosure. ## Impedance Match — 75 Ohm vs 50 Ohm This adapter is designed for 75 Ohm BNC systems — common in video, broadcast, and telecom — and is not electrically interchangeable with 50 Ohm BNC. Mating a 75 Ohm adapter into a 50 Ohm line creates a mismatch that degrades return loss and signal integrity above a few hundred MHz. The 031-9-75RFX is the 75 Ohm, right-angle variant in the 031-9 family; the 031-9-75-12G is the same form factor but rated to 12 GHz with a PTFE dielectric, while the 031-220N-75RFX is a straight bulkhead jack-to-jack adapter in the same impedance. ## Temperature Range and Materials The body is brass with nickel finish, the center contacts are gold-plated brass and phosphor bronze, and the dielectric is polyoxymethylene (POM) acetal. The dual bayonet-lock fastening on both ends secures the connection against vibration in field-installed cable runs.","metaTitle":"Amphenol 031-9-75RFX BNC Right Angle Adapter, 75 Ohm, 4 GHz","metaDescription":"Amphenol 031-9-75RFX BNC plug-to-jack right angle adapter, 75 Ohm impedance, 4 GHz max frequency, nickel-plated brass body, gold-plated center contacts.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Amphenol RF","Style":"Right Angle","Series":"-","Package":"Bulk","Features":"-","Includes":"-","Impedance":"75Ohm","Body Finish":"Nickel","Adapter Type":"Plug to Jack","Body Material":"Brass","Center Gender":"Female to Male","Mating Cycles":"-","Mounting Type":"Free Hanging (In-Line), Right Angle","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":"-","Ingress Protection":"-","Base Product Number":"031-9","Dielectric Material":"Polyoxymethylene (POM) Acetal","Operating Temperature":"-65°C~165°C","Center Contact Plating":"Gold","Center Contact Material":"Brass; Phosphor Bronze","Convert To (Adapter End)":"BNC Jack, Female Socket","Convert From (Adapter End)":"BNC Plug, Male Pin"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.9400","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/031-9-75RFX/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/031-9-75RFX","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/031-9-75RFX when reusing this data.
