Combining excellent electrical characteristics with robust mechanical stability, the Kinghelm KH-SMA-KWEQ5 SMA female connector passes a 48-hour neutral salt spray test, offering outstanding corrosion resistance and long-term durability in harsh environments. It is manufactured from premium metal materials with a full-thread interface to provide a secure mechanical lock, ensuring stable signal contact even under frequent mating or high-vibration conditions.

The right-angle design helps save space and supports flexible interconnection between multiple PCBs, making it especially suitable for equipment with strict dimensional and layout constraints. Capable of supporting RF signals up to several GHz, this connector ensures low signal loss and minimal reflection, making it ideal for antenna ports, wireless communication modules, test instruments, signal distributors, and RFID systems.

Kinghelm emphasizes durability and long-term reliability in the KH-SMA-KWEQ5. Its exceptional anti-corrosion performance makes it well-suited for outdoor environments, including coastal installations and telecom base stations, where exposure to moisture and salt is common. Positive feedback from customers across industries underscores its stable performance, making it a preferred choice among communication equipment manufacturers and R&D engineers.

Manufactured using advanced CNC machining processes, each connector maintains precise mechanical dimensions, enhancing assembly consistency and reducing downstream testing and maintenance costs. Every KH-SMA-KWEQ5 SMA female connector unit undergoes rigorous quality checks—including insertion force tests, contact resistance measurement, and high-frequency performance validation—ensuring compliance with industrial-grade standards.

As a leading RF connector supplier in China, Kinghelm not only offers the KH-SMA-KWEQ5 SMA jack but also a complete range of SMA plug connectors, including straight, right-angle, crimp-type, and nut-fixed options to meet various design and usage requirements. Kinghelm also provides RF coaxial cable assemblies, antenna solutions, and custom connector services, enabling clients to benefit from streamlined, integrated solutions from design through delivery.
