The snap-on fastening mates quickly with the matching QMA plug, though the 100-cycle rating means this is a moderate-duty interface, not a daily-remate production test port. ## Panel-mount kit — what comes in the bag This is a bulk-packaged kit: one QMA jack, one lockwasher, and one hex nut for front-side bulkhead mounting. The 480 V rating gives headroom if DC bias rides the RF line. ## Cable prep and termination — solder both ends Termination is solder-only: the center contact solders to the RG-402 center conductor, and the shield solders to the connector body. No crimp tool needed, but the semi-rigid cable requires careful strip lengths and a clean solder joint to avoid impedance bumps at the transition.","metaTitle":"Amphenol 930-122J-51S QMA Jack, 50 Ohm, 11 GHz, RG-402","metaDescription":"Amphenol 930-122J-51S QMA jack, female socket, 50 Ohm impedance, 11 GHz max, RG-402 semi-rigid cable, panel mount with snap-on coupling, 480 V, 100 cycles.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Amphenol RF","Series":"-","Package":"Bulk","Features":"-","Includes":"3 pcs - 1 Connector, 1 Lockwasher, 1 Nut","Impedance":"50Ohm","Body Finish":"Gold","Cable Group":"RG-402 (.141\\\" Semi Rigid)","Body Material":"Brass","Housing Color":"Gold","Mating Cycles":"100","Mounting Type":"Panel Mount","Connector Type":"Jack, Female Socket","Fastening Type":"Snap-On","Insertion Loss":"-","Product Status":"Active","Voltage Rating":"480 V","Connector Style":"QMA","Frequency - Max":"11 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Bulkhead - Front Side Nut","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"93012","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-40°C~85°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.3774","stockQuantity":20,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/176e3c2e495b82cf9a90b3544fd803b9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 930-122J-51S compatible with RG-402 cable?","answer":"Yes — the 930-122J-51S is specifically designed for RG-402 (.141\" semi-rigid) cable, with solder termination for both the center conductor and shield."},{"question":"What is the difference between 930-122J-51S and 930-122J-51P?","answer":"The 930-122J-51S is a jack (female socket), while the 930-122J-51P would be a plug (male pin) — they are mating halves, not alternatives.
