Description
N Jack (Female) Panel Connector | Screw-lock | Brass Body
The ROSNOL N2GFB50-2800A/94 is an N Jack (Female) panel connector developed for RF and microwave applications operating from DC to 11 GHz with a 50 Ω impedance. This connector features a 4-hole flange mount with a hole spacing of 18.24 mm (0.718 inch) and a solder cup terminal, providing robust mechanical fixation for panel and chassis installations. Electrical performance includes VSWR ≤ 1.20 (Return Loss ≥ 20.83 dB), insertion loss ≤ 0.015 × √F (GHz) dB, insulation resistance ≥ 5 GΩ, a working voltage of 500 V rms, and RF leakage ≥ 128 dB up to 1 GHz.The connector body is manufactured from brass with a copper–tin–zinc alloy composition to ensure mechanical rigidity and stable grounding characteristics. The center contact utilizes beryllium copper with gold plating over a non-magnetic nickel-phosphorus underplating to minimize contact resistance and ensure excellent RF transmission. A PTFE insulator provides stable dielectric performance, while the 4-hole flange design with 18.24 mm (0.718 inch) hole spacing enhances panel retention 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.
