Description
SMA Male Connector with Stub Terminal | Brass Body | Gold Plated | Epoxy Captivation
The ROSNOL SMA1GTA50-2490A-EC/111 is a rugged SMA male connector engineered for high-frequency RF applications. It operates from DC to 18 GHz with a 50 Ω impedance and VSWR ≤ 1.30. The connector includes a 2-hole flange mount and stub terminal with 12.22 mm (0.481 inch) hole spacing. It features a screw-lock coupling mechanism, soldered center contact, and epoxy captivation. Mechanical retention is rated at axial ≥ 27 N and radial ≥ 3 N·cm.The body and coupling nut are brass with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating. PTFE insulator and silicone rubber gasket ensure stable performance in harsh environments.
ROSNOL’s precision-engineered RF connectors offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All Rosnol RF components are precision-manufactured in ISO 9001-certified facilities, and are fully RoHS and REACH compliant, ensuring environmental safety and global regulatory alignment. Customization services for plating, materials, and mechanical design are available upon request.
