Description
SMA Series Female Connector Stub Terminal RF Connector Brass Body
The ROSNOL SMA2GFA50-2950A/91 is a precision SMA female connector with a 4-hole flange mount and 8.64mm (0.340 inch) hole spacing. It supports DC to 18 GHz frequency range with a 50 Ω impedance and an enhanced VSWR ≤ 1.2. The connector features a screw-lock coupling mechanism, soldered centre contact, stub terminal type, and mechanical captivated design with axial retention ≥ 27 N and radial retention ≥ 3 Ncm.This model utilizes a brass body with gold plating, complemented by a beryllium copper centre contact also gold-plated over non-magnetic nickel-phosphorus underplating. The insulator is PTFE, providing stable electrical insulation and performance.
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.
