It's built for controlled-impedance signal paths at 50 Ohms, with a usable bandwidth to 9 GHz — the limit before the interface's VSWR starts to climb. The Code D keying variant prevents cross-mating with other AUTOMATE codes (A, B, C, E, F, G, H, K, L) in the same harness, so the RF path stays pinned to the right channel. The latch lock fastening gives a positive audible click on mate, and the 25-cycle rating means this is a fit-and-forget connector for production harnesses, not a daily test port. ## Code D vs Code C — The Keying Difference The AUTOMATE series uses colour-coded keying variants to prevent mis-mating in multi-channel RF harnesses. The FM4-NDSP-PCB-1 carries Code D keying (violet and claret housing colours), while Code C uses a different key profile and colour. A Code D plug will not physically mate with a Code C receptacle — the keying pin position is non-negotiable. If your BOM calls for Code D, a Code C part will not insert, so the harness build stops at the connector.","metaTitle":"Amphenol RF FM4-NDSP-PCB-1 AUTOMATE Plug, 50 Ohm, 9 GHz","metaDescription":"Amphenol RF FM4-NDSP-PCB-1 AUTOMATE miniature coaxial plug, male pin, Code D keying, 50 Ohm impedance, 9 GHz max, 25 mating cycles, through-hole, Tape & Reel.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Amphenol RF","Series":"AUTOMATE™","Package":"Tape & Reel (TR)","Features":"Code D","Includes":"-","Impedance":"50 Ohms","Body Finish":"Tin","Cable Group":"-","Body Material":"Zinc Alloy","Housing Color":"Violet, Claret","Mating Cycles":"25","Mounting Type":"Through Hole","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","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":"$5.4795","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/ffe9e5555c982ae50e5bec3daf1a1fdd.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/FM4-NDSP-PCB-1/alternatives.json"},"ai":{"faq":[{"question":"Is the FM4-NDSP-PCB-1 suitable for 50 ohm impedance?","answer":"Yes, the FM4-NDSP-PCB-1 is rated for 50 Ohms nominal impedance, making it suitable for controlled-impedance RF signal paths up to 9 GHz."},{"question":"What is the mating cycle rating of the FM4-NDSP-PCB-1?","answer":"The FM4-NDSP-PCB-1 is rated for 25 mating cycles.
