Description
SMA Jack (Female) | Plug-in Centre Contact | Soldered Cable Entry | Stainless Steel Body | Epoxy Captivation
The ROSNOL SMA2EBF50-0085A-EC/9Q is an SMA Jack (Female) connector designed for broadband RF performance from DC to 18 GHz. Engineered with a controlled 50 Ω impedance, VSWR ≤ 1.25, insertion loss ≤ 0.04 × √F (GHz), and a working voltage of 480 V rms, this connector ensures stable high‑frequency transmission in precision RF and microwave assemblies. Electrical characteristics include insulation resistance ≥ 5 GΩ, center contact resistance ≤ 3 mΩ, outer contact resistance ≤ 2 mΩ, and power handling capability up to 200 W at 2 GHz under standard operating conditions. Its 4‑hole flange mount incorporates 8.64 mm (0.340 inch) hole spacing, enabling secure attachment to panels, housings, and RF cavity structures.Mechanical construction is optimized for durability, featuring a screw‑lock coupling mechanism with ≥ 500 mating cycles, axial centre‑contact captivation ≥ 27 N, and radial stability ≥ 3 Ncm. The connector integrates a solder‑type cable entry and a plug‑in style centre contact with epoxy captivation, ensuring stable mechanical retention and long‑term electrical reliability. Piece parts are constructed from high‑grade materials: the centre contact is gold‑plated beryllium copper 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 PTFE; and the gasket is silicone rubber for environmental sealing. Suitable cable types include .085, .086, RG405, Rosnol RSR‑085, RSF‑085, and EF405.
ROSNOL’s RF connectors deliver high performance at competitive pricing, offering a reliable alternative to leading European and American brands. All components are manufactured in ISO 9001‑certified facilities and fully comply with RoHS and REACH requirements. Customization services for materials, plating specifications, and mechanical configuration are available to accommodate specialized RF and microwave system integration needs.
