2.92mm Jack (Female) to 7mm Sexless Adapter, DC-18GHz VSWR1.15

2.92mm Jack (Female) to 7 mm Sexless | Straight Design | Screw-Lock | Stainless Steel Body

The ROSNOL AD-K2P7S5A/9X-9XX is a precision RF adapter for broadband applications from DC to 18 GHz with 50 ohm impedance. It achieves a VSWR of ≤1.15 and insertion loss of ≤0.04 × √F GHz, ensuring excellent return loss. Electrical ratings include 750 Vrms test voltage, 250 Vrms working voltage, and RF leakage of ≥100 dB up to 1 GHz. Screw-lock coupling provides secure engagement with recommended torque of 0.80 to 1.10 Nm on the 2.92mm side and 1.36 Nm on the 7 mm side. Center contact captivation is ≥28 N, and mechanical durability is ≥500 mating cycles.

Materials and plating are selected for long-term stability. 7 mm side: beryllium copper center contact with 3 microinch gold plating over 80 microinch non-magnetic nickel-phosphorus underplating, passivated stainless steel body and coupling nut, PS insulator. 2.92mm side: beryllium copper center contact with the same gold over nickel-phosphorus plating stack, passivated stainless steel body, PS insulator. The adapter performs reliably from −55°C to +70°C.

ROSNOL’s RF adapters deliver consistent quality and value, making them a reliable alternative to leading brands in Europe and the USA. All ROSNOL components are manufactured in ISO 9001 certified facilities and fully comply with RoHS and REACH regulations. Customization services for materials, plating, and mechanical design are available to meet specialized interconnect requirements.
