MCX Snap-On Jack for Non-Magnetic RF Paths
The 919-NM109J-51P: The snap-on fastening type gives a quick, positive mate with the matching MCX plug — no coupling nut to torque, just push until it clicks. 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.
