Description
SMA Female Connector with Stub Terminal | Solder Attachment | Stainless Steel Body | Epoxy Captivation
The ROSNOL SMA2GTA50-2740A-EC/9Q RF Connector is engineered for high-performance applications requiring 50Ω impedance and broad frequency coverage from DC to 18 GHz. Featuring a 2-hole flange mount with 12.22mm (0.481 inch) hole spacing and a stub terminal design, it ensures reliable mechanical integration. The screw-lock coupling mechanism supports ≥ 500 mating cycles, while maintaining excellent signal integrity with VSWR ≤ 1.30 (≥ 17.7 dB) and insertion loss ≤ 0.05√F(GHz) dB. It withstands up to 1000 V rms test voltage and is constructed with a stainless steel body and beryllium copper center contact, both gold-plated over non-magnetic nickel-phosphorus. PTFE insulation provides thermal stability.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.
