Description
2.92mm Plug (Male) | Solder Attachment | 4-Hole Flange Mount | Stainless Steel Body
The ROSNOL K1GFA50-1974A/9XX is a precision-engineered 2.92mm plug connector designed for high-frequency RF systems requiring secure solder attachment and flange mounting. Featuring a 4-hole flange with 8.6 mm (0.339 inch) hole spacing, this connector supports DC to 50 GHz with 50 Ω impedance, VSWR ≤ 1.15 (≥ 23.1 dB return loss), and insertion loss ≤ 0.04√f (GHz) dB. Electrical integrity includes insulation resistance ≥ 5 GΩ, center contact resistance ≤ 3 mΩ, and RF leakage ≥ 85 dB up to 1 GHz. Rated for 750 V rms test voltage and 250 V rms working voltage, it ensures reliable performance in demanding RF environments.Constructed for durability, the center contact is beryllium copper with gold plating over non-magnetic nickel-phosphorus underplating, while the body and coupling nut are stainless steel with passivated finish. The insulator is PEI/PTFE for superior dielectric properties. Mechanical features include screw-lock coupling, ≥ 500 mating cycles, center contact captivation ≥ 20 N, and recommended torque of 0.80–1.10 Nm. The captivated stub terminal design enhances mechanical stability for rugged applications.
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 manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring environmental safety and global standards. Customization services for plating, materials, and mechanical design are available upon request.
