SMA Jack (Female) Straight Connector 4 Hole Flange, 8.64mm (.340 inch) DC-18GHz VSWR1.30

SMA Jack (Female) | Flat End | 4-Hole Flange Mount | Stainless Steel Body

The ROSNOL SMA2GFD50-1200A/9X is a precision SMA jack (female) connector designed for stable RF performance from DC to 18 GHz. This 4-hole flange-mount model features an 8.64 mm (0.340 inch) hole spacing and a secure screw-lock coupling mechanism. With a 50 Ω impedance, VSWR ≤ 1.30, and insertion loss ≤ 0.05 × √F(GHz), it ensures signal integrity in demanding environments. Mechanical attributes include a soldered center contact, flat terminal structure, epoxy-free mechanical captivation, and recommended torque between 0.8 Nm and 1.1 Nm, offering durable and repeatable mating performance.

Constructed with high-reliability materials, the SMA2GFD50-1200A/9X uses a beryllium copper center contact with gold plating over a non-magnetic nickel-phosphorus underlayer for excellent conductivity and corrosion resistance. The stainless-steel body features passivation for enhanced durability, and the PTFE insulator ensures stable dielectric performance across wide temperature ranges. This connector is well-suited for RF, microwave, instrumentation, telecommunications, aerospace, and precision test equipment applications requiring robust flange-mount connectivity.

ROSNOL RF components are engineered to deliver high-quality performance at competitive pricing, making them a cost-effective alternative to leading European and American brands. All products are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring adherence to global environmental and safety standards. Customized solutions—including special materials, plating options, and mechanical configurations—are available to meet diverse RF system requirements.
