SMA Plug (Male) Right-Angle Cable Connector for RSR-141, RSF-141, RSF-141-FEP, EF-402, RG-402/U, DC-12.4GHz VSWR1.25

SMA Plug (Male) | Soldered Cable Entry | Screw-lock | Stainless Steel Body

The ROSNOL SMA1E59-0141A/1QX is an SMA Plug (Male) right-angle connector engineered for broadband RF performance from DC to 12.4 GHz. With a controlled 50 Ω impedance, VSWR ≤ 1.25, and insertion loss ≤ 0.04 × √F (GHz), this connector ensures stable high‑frequency transmission in microwave modules, compact RF assemblies, and precision coaxial interconnects using .141‑class semi‑rigid or hand‑formable cables. Electrical characteristics include insulation resistance ≥ 5 GΩ, center contact resistance ≤ 3 mΩ, outer contact resistance ≤ 2 mΩ, a working voltage of 480 V rms, and power handling up to 200 W at 2 GHz under standard operating conditions.

Mechanical structure is optimized for durability and reliable mating performance: the screw‑lock coupling mechanism supports ≥ 500 mating cycles, the coupling‑nut retention is rated at ≥ 270 N, and the axial center‑contact captivation is specified at ≥ 20 N. The connector features a solder‑type cable entry and soldered center‑pin configuration, ensuring secure mechanical attachment and stable electrical continuity in assembly production. Its right‑angle form factor enables space‑efficient routing in dense RF layouts.

Piece parts are manufactured to achieve long‑term reliability and broadband stability: the centre contact is gold‑plated brass with a non‑magnetic nickel‑phosphorus underplate; the body is stainless steel with gold plating over a non‑magnetic nickel‑phosphorus underlayer; the insulator is high‑grade PTFE; the gasket is silicone rubber; and the coupling nut is passivated stainless steel. Suitable cable types include RSR‑141, RSF‑141, RSF‑141‑FEP, EF402, and RG402/U. ROSNOL’s RF connectors are produced in ISO 9001‑certified facilities, fully comply with RoHS and REACH requirements, and provide a cost‑effective alternative to leading European and American brands. Customization options for materials, plating, and mechanical design are available to meet specialized RF and microwave system needs.
