The 1.0/2.3 interface is the European-born standard for professional video patching and distribution, distinct from the 50 Ohm BNC or SMA connectors common in RF test gear. ## The 75 Ohm Impedance — Why It Matters At 75 Ohm, this connector is impedance-matched for composite video, SDI, and CATV distribution — not the 50 Ohm world of radio transmitters or test instruments. The 75 Ohm characteristic impedance minimizes signal reflection on coaxial cables like RG-59 or RG-6, which is why broadcast racks and head-end equipment use this interface. The 3 GHz frequency ceiling covers 4K/8K SDI signals and DOCSIS 3.1 upstream bands, though the practical limit in a real patch panel is often lower due to cable losses. ## Mounting and Termination — What You Get in the Box The package includes two pieces: the connector body and a hex nut for bulkhead mounting. There is no lockwasher included — the 282133-75 peer part adds one, so if your panel sees vibration, order that variant or supply your own star washer. The mounting feature is bulkhead front-side nut: you drop the connector through a panel cutout from the front and tighten the nut from behind. The dielectric is PTFE (Teflon), which gives stable impedance across the -40°C to 155°C operating range. ## 500 Mating Cycles — What That Means on Site The gold-on-brass body finish resists corrosion in humid head-end rooms, and the push-pull fastening lets you disconnect without tools.","metaTitle":"Amphenol RF 282139-75 1.0/2.3 Receptacle, 75 Ohm, 3 GHz","metaDescription":"Amphenol RF 282139-75 1.0/2.3 receptacle, 75 Ohm impedance, female socket, panel mount right angle, gold body, rated to 3 GHz, 500 mating cycles.","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":"2 pcs - 1 Connector, 1 Nut","Impedance":"75Ohm","Body Finish":"Gold","Cable Group":"-","Body Material":"Brass","Housing Color":"Gold","Mating Cycles":"500","Mounting Type":"Panel Mount, Through Hole, Right Angle","Connector Type":"Receptacle, Female Socket","Fastening Type":"Push-Pull","Insertion Loss":"-","Product Status":"Active","Voltage Rating":"250 V","Connector Style":"1.0/2.3","Frequency - Max":"3 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Bulkhead - Front Side Nut","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"282139","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-40°C~155°C","Center Contact Plating":"Gold","Center Contact Material":"Brass; Phosphor Bronze"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.5000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/507be897d3b3d01266f6405dd3979802.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/282139-75/alternatives.json"},"ai":{"faq":[{"question":"What is the mounting style of 282139-75?","answer":"It is a panel mount, through-hole, right-angle connector with a bulkhead front-side nut mounting feature.
