N Plug (Male) to MCX Jack (Female) Bulkhead Adapter, DC-6GHz VSWR1.20

N Plug (Male) to MCX Jack (Female) | Bulkhead Adapter | Screw-Lock | Brass Body

The ROSNOL AD-N1M25A-BH/944-91 is a bulkhead RF adapter designed for secure interconnection between N plug male and MCX jack female interfaces. It operates from DC to 6 GHz with 50-ohm impedance, VSWR ≤ 1.20, and insertion loss ≤ 0.05√F (GHz) dB. Electrical specifications include insulation resistance ≥ 1 GΩ, test voltage 750 V rms, working voltage 335 V rms, and current handling up to 1.5 A DC. The adapter features a screw-lock coupling on the N side and snap-lock on the MCX side, ensuring axial captivation ≥ 28 N and durability for at least 500 mating cycles. Recommended torque for the N side is 0.7–1.1 Nm, with a maximum coupling torque of 1.7 Nm, delivering robust mechanical reliability.

Material construction ensures superior performance: the MCX center contact is beryllium copper with gold plating over a non-magnetic nickel-phosphorus underlayer, and its body is brass with nickel underplating. The N side uses beryllium copper for the center contact with gold plating over nickel-phosphorus, and a brass body finished with copper-tin-zinc alloy. Both connectors employ PTFE insulators and a silicone rubber gasket for environmental sealing. This adapter withstands temperatures from -55°C to +155°C and offers excellent corrosion resistance for demanding RF environments.

ROSNOL’s precision-engineered RF adapters deliver high quality and reliable performance at competitive pricing, making them an ideal alternative to leading European and American brands. All ROSNOL components are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH regulations. Customization services for materials, plating, and mechanical design are available to meet specialized interconnect requirements.
