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

SMA Jack (Female) | Solder End | 4-Hole Flange Mount | Stainless Steel Body | Epoxy Captivation

The ROSNOL SMA2GFA50-2740C-EC/HX is engineered for high-frequency RF systems requiring robust sealing and panel mounting. It provides 50 Ω impedance and operates from DC to 18 GHz with VSWR ≤ 1.30 for consistent signal performance. The screw-lock coupling mechanism ensures secure mating and durability with ≥500 cycles. Key dimensions include an overall length of 27.4 mm \[1.079 in], flange size of 15 mm \[.591 in], mounting holes of Ø2.6 mm \[.102 in], and hole spacing of 8.64 mm \[.340 in]. The thread specification is 1/4-36 UNS, and the connector withstands temperatures from -65°C to +165°C.

The center contact is phosphor bronze with gold plating over a nickel-phosphorus underplate, while the body is stainless steel with passivated finish for enhanced corrosion resistance. The insulator is PTFE, ensuring excellent dielectric strength. Epoxy captivation provides additional sealing for harsh environments, and the soldered stub terminal guarantees secure electrical connection and mechanical integrity.
