Description
SMA Female Connector with Stub Terminal | Brass Body | Gold Plated | Mechanical Captivation
The ROSNOL SMA2GFA50-1161A/91 is a precision SMA female connector designed for RF applications requiring robust mechanical retention and high conductivity. It supports DC to 18 GHz with a 50 Ω impedance and VSWR ≤ 1.30. The connector features a 4-hole flange mount and stub terminal with 8.64 mm (0.340 inch) hole spacing. It utilizes a screw-lock coupling mechanism, a soldered center contact, and mechanical captivation. Axial retention is ≥ 27 N and radial retention is ≥ 3 N·cm.The center contact is beryllium copper with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating. The body is brass with the same plating structure. PTFE insulator ensures excellent dielectric performance across a wide temperature range.
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.
