The Kinghelm KH-RJ45-58-8P8C is a standard-compliant 8P8C RJ45 jack that utilizes through-hole technology, allowing for fast soldering and efficient mass production. Its elongated housing enhances mechanical strength and torsion resistance, making it ideal for environments with frequent plugging and unplugging or mechanical vibrations. Compared to conventional short-body RJ45 connectors, the long-body design offers greater structural advantages in equipment port layouts and is widely used in high-end routers, switches, network servers, and industrial control terminals.

Designed with a right-angle (side entry) pin configuration, the KH-RJ45-58-8P8C is optimized for edge-mount PCB applications, ensuring a compact fit with the motherboard while saving vertical space and streamlining internal wiring. Its integrated metal shielding provides excellent EMI protection, effectively blocking external interference and ensuring stable, accurate data transmission—particularly valuable in industrial environments with complex electromagnetic conditions.

In terms of electrical performance, this RJ45 jack offers a maximum rated current of 1.5A and a rated voltage of 125V, meeting the power demands of mainstream networking and control systems. The contact resistance is controlled within 40mΩ max, significantly minimizing signal loss and enhancing transmission efficiency. Additionally, with an insulation resistance of 500MΩ min, it ensures robust electrical isolation, helping to prevent leakage and signal interference for safer, more secure communication.

The KH-RJ45-58-8P8C RJ45 jack is designed without LED indicators, making it suitable for streamlined device designs while reducing energy consumption and component complexity. It comes in tape-and-reel packaging, facilitating automated pick-and-place operations and compatibility with modern high-efficiency assembly lines.

Weighing just 4.959g per unit, the jack maintains mechanical durability while minimizing system load, offering greater design flexibility. Backed by Kinghelm’s stringent manufacturing standards—from material selection and pin precision to product consistency—the KH-RJ45-58-8P8C excels in reliability, compatibility, and service life.
