Description
SMA Jack (Female) Panel Connector | Screw-lock | Stainless Steel Body
The ROSNOL SMA2GTA50-1555A/9X is an SMA Jack (Female) panel-mounted RF connector designed for 50 Ω systems operating from DC to 18 GHz. This connector features a 2-hole flange mount with a hole spacing of 12.22 mm (0.481 inch) and a stub solder terminal, providing reliable mechanical attachment for RF panels and enclosures. Electrical performance includes VSWR ≤ 1.20 (Return Loss ≥ 20.83 dB), insertion loss ≤ 0.04 × √F (GHz) dB, insulation resistance ≥ 5 GΩ, and a working voltage of 480 V rms, supporting stable high-frequency signal transmission.The connector body is manufactured from passivated stainless steel to provide mechanical strength and corrosion resistance. A gold-plated beryllium copper center contact with non-magnetic nickel-phosphorus underplating ensures low contact resistance and consistent RF performance. A PTFE insulator maintains dielectric stability, while the 2-hole flange structure with defined hole spacing supports repeatable panel alignment and long-term mechanical reliability.
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 global environmental and safety standards. Customization services for plating, materials, and mechanical design are available upon request.
