Description
2.92mm Plug (Male) to 1.85mm Jack (Female) | Straight Design | Screw-Lock | Stainless Steel Body
The ROSNOL AD-K1V25A/9XX-9X is engineered for high-frequency RF systems, supporting DC to 40 GHz with a 50 ohm impedance. It delivers a VSWR of ≤1.15 and insertion loss of ≤0.05 × √F GHz, ensuring optimal signal integrity. Electrical ratings include insulation resistance ≥5 GΩ, test voltage 500 Vrms, working voltage 150 Vrms, and RF leakage ≥100 dB up to 1 GHz. Screw-lock coupling provides secure engagement with recommended torque of 0.80 to 1.10 Nm, while center contact captivation meets ≥20 N. Mechanical durability exceeds 500 mating cycles.Materials and plating are optimized for conductivity and durability. Both sides feature beryllium copper center contacts with gold plating over nickel-phosphorus underplating, stainless steel bodies and coupling nuts passivated, and PEI insulators for dielectric stability. The adapter maintains stable performance from −55°C to +165°C.
ROSNOL’s RF adapters deliver consistent quality and cost efficiency, making them a reliable alternative to leading European and American brands. 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.
