Description
2.92mm Jack (Female) | Compression Mount | Screw-lock | Stainless Steel Body
The ROSNOL K2LA50-1092B/9Q connector is a high-precision 2.92mm Jack (Female) designed for compression mount applications in high-speed stripline PCB systems. It supports DC to 40 GHz frequency range with 50 Ω impedance, VSWR ≤ 1.43 (≥ 15.04 dB return loss), and insertion loss ≤ 0.04 × √F (GHz) dB. Electrical ratings include insulation resistance ≥ 5 GΩ, test voltage 750 V rms, and RF leakage ≥ 100 dB up to 1 GHz. Mechanical features include screw-lock coupling, ≥ 500 mating cycles, axial center contact captivation ≥ 20 N, and torque ratings of 0.80–1.10 Nm recommended (1.7 Nm max), with typical screw torque of 0.15 Nm.Material construction includes a beryllium copper center contact with gold plating over non-magnetic nickel-phosphorus underplating. The body is stainless steel with gold plating, and the insulator is PEI for superior dielectric performance.
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.
