Description
N Jack (Female) | 4 Hole Flange Mount | Soldered and Clamped Cable Entry | Screw-lock | Brass Body
The ROSNOL N2KBF50-0141A1/94 is a 4 hole flange-mounted N jack (female) connector designed for panel-mounted RF cable assemblies in 50 Ω systems, supporting operation from DC to 11 GHz. This connector features a screw-lock coupling mechanism to provide secure mating and stable RF performance in high-power transmission environments. The 4 hole flange mount incorporates a hole spacing of 18.25 mm (.719 inch), enabling precise and secure panel installation. A soldered center contact combined with a solder clamp cable entry ensures reliable electrical continuity, mechanical retention, and consistent impedance control. With a VSWR of ≤ 1.20 and a mechanical life rated for a minimum of 500 mating cycles, this connector is suited for demanding RF and microwave applications requiring long-term durability.The connector body is manufactured from brass with a copper–tin–zinc alloy composition to deliver excellent mechanical strength and corrosion resistance. The center contact is made of beryllium copper with gold plating over a non-magnetic nickel-phosphorus underplating to achieve low contact resistance and long-term electrical stability. A PTFE insulator is used to maintain stable dielectric performance across the operating frequency range, supporting reliable signal transmission in high-frequency applications. The N2KBF50-0141A1/94 is compatible with .141 RSF, .141 RSR, RG402, and EF402 cable types.
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.
