The beryllium copper body and centre contact, both gold-plated, are specified as non-magnetic, which makes this jack a fit for MRI-adjacent equipment, NMR probes, or any instrumentation where ferrous materials would distort the field. Rated to 6 GHz max frequency. The 0.1 dB insertion loss at 6 GHz is a tight spec. ## Beryllium Copper and Non-Magnetic Construction Beryllium copper is the material for both the body and the centre contact. It gives good spring properties for the snap-on retention and the socket beam, and its non-magnetic characteristic is the reason this part carries the NM suffix. The -40°C to 155°C operating range covers industrial and lab environments, including autoclave or bake-out cycles if the connector is left unmated.","metaTitle":"Amphenol RF 919-NM109J-51P MCX Jack, 50 Ohm, 6 GHz","metaDescription":"Amphenol RF 919-NM109J-51P MCX jack, female socket, 50 Ohm, 6 GHz max, snap-on, gold beryllium copper body, non-magnetic, 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":"Non-Magnetic","Includes":"-","Impedance":"50Ohm","Body Finish":"Gold","Cable Group":"-","Body Material":"Beryllium Copper","Housing Color":"Gold","Mating Cycles":"500","Mounting Type":"Through Hole","Connector Type":"Jack, Female Socket","Fastening Type":"Snap-On","Insertion Loss":"0.1dB","Product Status":"Active","Connector Style":"MCX","Frequency - Max":"6 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"919NM","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-40°C~155°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.1500","stockQuantity":26,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b6be305512c81cea52611af051f4940c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What connector mates with 919-NM109J-51P?","answer":"This is an MCX jack (female socket) with a snap-on fastening type.
