Description
2.92mm Plug (Male) to Precision SMA Plug | Straight Design | Screw-Lock | Brass Body
The ROSNOL AD-K1PCA15A/111-111 is a precision RF adapter operating from DC to 27 GHz with 50 ohm impedance. It delivers a VSWR of ≤1.15 and insertion loss of ≤0.05 × √F GHz, ensuring excellent return loss performance. Electrical specifications include dielectric withstanding voltage of 750 Vrms, test voltage of 500 Vrms, and working voltage of 750 Vrms. 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 is rated at ≥500 mating cycles.Materials and plating are optimized for conductivity and durability. Both sides use brass components with 3 microinch gold plating over 80 microinch non-magnetic nickel-phosphorus underplating. Precision SMA side: brass center contact and body gold plated, PTFE insulator, brass coupling nut gold plated. 2.92mm side: brass center contact and body gold plated, PS insulator, silicone rubber gasket, brass coupling nut gold plated. The adapter maintains stable performance from −55°C to +125°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.
