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

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

The ROSNOL AD-K1P7S5A/9XX-9XX is a high-frequency RF adapter operating from DC to 18 GHz with a 50 ohm impedance. It delivers a VSWR of ≤1.15 and insertion loss of ≤0.04 × √F GHz, minimizing signal degradation. Test voltage is 750 Vrms and working voltage 250 Vrms, with RF leakage of ≥100 dB up to 1 GHz. Screw-lock coupling on both sides ensures 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 for reliable performance.

Engineered with premium materials, the 7 mm side uses a beryllium copper center contact with 3 microinch gold plating over 80 microinch non-magnetic nickel-phosphorus underplating, a passivated stainless steel body and coupling nut, and a PS insulator. The 2.92mm side mirrors this plating stack on a beryllium copper center contact, with passivated stainless steel body and coupling nut and a PS insulator. The adapter operates reliably from −55°C to +70°C.

ROSNOL’s RF adapters combine precision engineering with cost efficiency, offering a competitive alternative to major European and American brands. All products are manufactured under ISO 9001 certified processes and fully comply with RoHS and REACH. Customization for materials, plating, and mechanical design is available to support specialized interconnect needs.
