Gold-on-beryllium copper is a standard high-cycle combination — the beryllium copper provides spring retention, and the gold prevents oxidation at the mating interface. For a panel-mounted receptacle that may be disconnected during equipment servicing, 500 cycles is generous; for a test-port connector that sees daily connect-disconnect, it is adequate for several years of routine use. The nickel-plated brass body is corrosion-resistant but not intended for submersion — the threaded fastening and bulkhead nut provide a mechanical seal against dust and splash, not a waterproof IP rating. ## Mounting Hardware and Installation The lockwasher sits between the panel and the nut to prevent loosening under vibration. The mounting feature is bulkhead rear-side nut, meaning the connector body is inserted from the outside of the panel and the nut is tightened from the inside. The center contact uses a solder cup termination, which accepts a tinned wire end or a pre-tinned center conductor. No crimp tool is required.","metaTitle":"Amphenol RF 901-9889-RFX SMA Receptacle, 50 Ohm, 18 GHz","metaDescription":"Amphenol RF 901-9889-RFX SMA receptacle, female socket, 50 Ohm, DC to 18 GHz, 500 mating cycles, panel mount with bulkhead nut and lockwasher included.","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":"3 pcs - 1 Connector, 1 Lockwasher, 1 Nut","Impedance":"50Ohm","Body Finish":"Nickel","Cable Group":"-","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"500","Mounting Type":"Panel Mount","Connector Type":"Receptacle, Female Socket","Fastening Type":"Threaded","Insertion Loss":"-","Product Status":"Active","Connector Style":"SMA","Frequency - Max":"18 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Bulkhead - Rear Side Nut","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"901-98","Contact Termination":"Solder Cup","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C~165°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.8500","stockQuantity":24,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/a2dd99b056450458efbb126c32750955.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the specifications of 901-9889-RFX?","answer":"The 901-9889-RFX is an SMA receptacle, female socket, 50 Ohm impedance, rated DC to 18 GHz, 500 mating cycles, panel mount with bulkhead rear-side nut, solder cup center contact termination, gold-plated beryllium copper center contact, nickel-plated brass body, PTFE dielectric, and includes the connector, lockwasher, and nut."},{"question":"Does 901-9889-RFX include mounting hardware?","answer":"Yes, the 901-9889-RFX includes a lockwasher and a bulkhead nut as part of the three-piece assembly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/901-9889-RFX","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/901-9889-RFX when reusing this data.
