CAT5e Shielded External Communication Parallel Cable for New Energy Systems

This external communication parallel cable is designed to solve signal interference and environmental challenges in new energy applications. The core utilizes CAT.5E 4P*26AWG shielded wire with high-purity tinned copper, which significantly reduces DC resistance and optimizes current carrying capacity. By minimizing energy loss during transmission, it ensures high-efficiency communication between parallel units. 

The harness is terminated with precision WCON industrial connectors on one end and an RUV Connet RJ45 M20.5 waterproof interface on the other, featuring a secure screw-locking mechanism and dust cap. This design guarantees consistent performance and effective heat dissipation, even under continuous operation.

Key Features & Benefits

• High-Fidelity Transmission: Features high-purity tinned copper conductors that achieve ultra-low DC resistance, maximizing signal integrity and reducing energy loss during data transfer.
• Robust EMI Protection: The CAT.5E shielded design effectively blocks electromagnetic interference, essential for stable communication in high-voltage inverter and battery environments.
• IP67 Waterproof Reliability: Equipped with RUV Connet RJ45 M20.5 connectors and protective dust caps, ensuring a watertight seal for outdoor or humid industrial conditions.
• Optimized Thermal Performance: Scientific wire gauge selection and precision crimping control temperature rise, ensuring performance does not degrade over time.
• Fully Customizable: Available in custom lengths (standard L=530/250/70mm) and pinout configurations to match specific BMS or inverter interface definitions.
