Yihetai provides custom RJ45 Ethernet cable assembly solutions according to your drawings, samples, cable specifications and application requirements.Our custom RJ45 Ethernet cable assemblies are widely used in automation equipment, communication devices and industrial wire harness assemblies for reliable data transmission.

What Is RJ45/Ethernet Cable Assembly?

RJ45/Ethernet cable assembly is a customized cable or wire assembly featuring RJ45 connectors for Ethernet networking, enabling high-speed data transmission up to Gigabit speeds. It meets specific electrical, structural, and installation needs like Cat5e, Cat6, or Cat6a standards with twisted pair wiring for reduced interference.

Compared with standard patch cords, a custom RJ45/Ethernet cable assembly can be designed for specific routing space, connector orientation, environmental resistance, cable flexibility, shielding performance, and assembly requirements. This makes it more suitable for OEM equipment, industrial cabinets, machine wiring, panel installations, and special applications where standard network cables do not fit well.
