It carries a male pin contact and uses a Code D keying feature — that color-coded violet/claret housing and latch lock prevent cross-mating with other Fakra codes in a multi-connector harness. The right-angle through-hole mounting puts the plug parallel to the board, saving height in a tight enclosure. ## What the 50 Ohm and 9 GHz Ratings Mean for the RF Path The 50 Ohm impedance is standard for RF signal chains — antenna feeds, telematics modules, and GNSS receivers all expect a 50 Ohm transmission line. The 9 GHz max frequency covers the full 5 GHz Wi-Fi band and most automotive radar bands, with headroom for emerging V2X channels. The LCP dielectric and brass/zinc alloy body with tin finish keep the return loss in check across that band; the shield termination is soldered to the PCB ground plane, so the launch impedance stays clean if the footprint matches the recommended land pattern. ## Code D Keying — Why It Matters in a Multi-Connector Harness Fakra connectors come in color-coded keying variants — Code A, B, C, D, Z, etc. — each with a unique housing shape and latch position. The FM4-NDRP-PCB-1 uses Code D, which means it physically cannot mate with a Code A or Code B receptacle. In a vehicle or equipment harness carrying multiple RF signals (e.g., GPS, cellular, satellite radio), the keying eliminates mis-mating at the assembly line or during field service.","metaTitle":"Amphenol RF FM4-NDRP-PCB-1, 50 Ohm Fakra Plug, 9 GHz, Code D","metaDescription":"Amphenol RF AUTOMATE series Fakra plug, male pin, 50 Ohm, 9 GHz max, Code D keying, through-hole right-angle mount, gold center contact, active production","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":"Tape & Reel (TR)","Features":"Code D","Includes":"-","Impedance":"50Ohm","Body Finish":"Tin","Cable Group":"-","Body Material":"Brass, Zinc Alloy","Housing Color":"Violet, Claret","Mating Cycles":"25","Mounting Type":"Through Hole, Right Angle","Connector Type":"Plug, Male Pin","Fastening Type":"Latch Lock","Insertion Loss":"-","Product Status":"Active","Connector Style":"Miniature Coaxial, Fakra, Quadraxial","Frequency - Max":"9 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"FM4-NDRP","Contact Termination":"Solder","Dielectric Material":"Liquid Crystal Polymer (LCP)","Operating Temperature":"-40°C~105°C","Center Contact Plating":"Gold","Center Contact Material":"Copper Alloy"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.3993","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/fc42fe4f8ab39cd3b983441e68011b23.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/FM4-NDRP-PCB-1/alternatives.json"},"ai":{"faq":[{"question":"What cable does FM4-NDRP-PCB-1 work with?","answer":"The FM4-NDRP-PCB-1 is a PCB-mount plug, not a cable plug.
