Verified by authoritative testing institutions, the salt spray resistance duration of this connector reaches 720 hours — far exceeding the industry standard of 200-500 hours for conventional products — providing a more reliable solution for equipment connection in harsh environments. This connector adopts a special surface treatment process and high-performance metal materials. In tests simulating extreme environments such as high salt spray in marine areas and industrial corrosive gases, it not only maintains stable electrical conductivity but also effectively resists the oxidation and corrosion of metal components, significantly reducing the maintenance frequency and replacement costs of equipment. It is widely applicable to fields with strict requirements for environmental resistance, including marine engineering, new energy photovoltaics, automotive electronics, and outdoor communication base stations, and can meet the demand for stable operation in long-term outdoor or high-corrosion scenarios. The successful development of this new product marks another step forward for our company in the R&D field of connector environmental resistance performance. In the future, we will continue to focus on the technological innovation of high-end connectors and provide better connection solutions for the equipment upgrading of various industries.

The TNC connector, short for Threaded Neill–Concelman, represents one of the most robust and reliable solutions within the RF coaxial connector family. Unlike bayonet-style connectors, the TNC employs a threaded coupling mechanism, which ensures a secure fit even in environments subject to vibration, mechanical stress, and harsh weather conditions. This design advantage makes it particularly well-suited for applications where signal stability and mechanical durability are paramount. The TNC Male RF Coaxial Connector – Straight Type, offered by Sipu RF, is engineered in compliance with internationally recognized standards, including MIL-C-39012 and IEC 60169-17. Such compliance guarantees not only reliable electrical performance but also interchangeability with comparable international products, which is a critical factor in global supply chains. The connector supports a broad frequency range extending from DC up to 11 GHz, thereby meeting the requirements of both traditional communication systems and modern high-frequency applications. From a technical perspective, the connector maintains a characteristic impedance of 50 ohms and demonstrates excellent electrical stability with a VSWR of 1.3 or less. It also withstands dielectric voltages of up to 1500 V and provides insulation resistance greater than 5000 MΩ, ensuring safety and performance in demanding conditions. The insertion loss remains low, measured at no more than 0.06√F (GHz) dB, which is essential for minimizing signal degradation over extended frequencies. Mechanically, the connector is built to endure a minimum of 500 mating cycles, reflecting its suitability for both laboratory testing and field deployment. The choice of materials further enhances performance and longevity. The center conductor is made of brass with gold plating to optimize conductivity and reduce corrosion risk, while the insulator employs PTFE for its excellent dielectric properties and thermal stability. The outer conductor is nickel-plated brass, offering mechanical strength and resistance to wear, and a silicon rubber sealing ring ensures environmental protection for outdoor use. Practical applications of the TNC connector extend across mobile communication equipment, antennas, navigation systems, radar technologies, and general RF systems where reliability cannot be compromised. Whether in civilian telecommunications or defense-grade installations, the TNC connector continues to serve as an industry standard for stable, threaded RF connections. Sipu RF is committed to providing both standard and customized TNC solutions. Our product range includes straight and right-angle designs, plug and jack variations, and reverse polarity configurations to suit diverse engineering needs. With certification under ISO9001, RoHS, and CE, our connectors combine global quality standards with flexible manufacturing capabilities. For engineers and procurement professionals seeking dependable RF connectivity, the TNC connector remains a proven and versatile choice. At Sipu RF, we strive to ensure that every connector not only meets but exceeds expectations for performance, durability, and compatibility in today’s demanding RF environments.
