Description
Non-Magnetic TNC Jack (Female) Panel Connector | Screw-lock | Brass Body
The ROSNOL NMTNC2GFA50-2880B/94 is a non‑magnetic TNC Jack (Female) panel connector specified for 50 Ω operation from DC to 4 GHz. It uses a 4-hole flange mount with hole spacing of 12.7 mm (0.500 inch) and a stub terminal for dependable panel and chassis installations. Electrical metrics include VSWR ≤ 1.09 (Return Loss ≥ 27.32 dB), insertion loss ≤ 0.03 × √F (GHz) dB, insulation resistance ≥ 5 GΩ, center contact resistance ≤ 1.5 mΩ, outer contact resistance ≤ 1 mΩ, working voltage 500 V rms, test voltage 1500 V rms, and power handling of 300 W @ 2 GHz.A brass body provides robust mechanical strength and corrosion resistance, while the center contact is beryllium copper with gold plating over a non‑magnetic nickel–phosphorus underplating to ensure low contact resistance and stable conductivity. A PTFE insulator maintains dielectric integrity, and a silicone rubber gasket supports flange sealing. The non‑magnetic construction and 4‑hole flange with 12.7 mm (0.500 inch) hole spacing provide secure, repeatable panel alignment for precision RF systems.
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 environmental safety and global regulatory alignment. Customization services for plating, materials, and mechanical design are available upon request.
