Structural Design & Signal Benefits
1. Dual Twisted Pair Design
The two twisted pairs help minimize signal crosstalk and maintain balanced transmission performance, making the cable suitable for RS485 differential communication systems.
2. Advanced Shielding System
The cable combines:
- Aluminum foil shielding
- Tinned copper braid shielding
- Drain wire grounding structure
- This layered shielding design provides excellent protection against external electromagnetic interference and improves communication stability in industrial environments.
3. Stable Electrical Performance
The cable is engineered with controlled impedance of:
120Ω ±12Ω
which matches typical RS485 transmission requirements and helps reduce signal reflection during high-speed communication.
4. Durable TPE Outer Jacket
The flexible TPE jacket offers:
- Good mechanical protection
- Excellent flexibility
- Resistance against environmental stress
- Easy installation in complex wiring environments
Installation & Performance Considerations
Installation Recommendations
- Maintain correct polarity when connecting RS485 A/B communication lines.
- Avoid routing parallel with high-voltage power cables.
- Connect shielding according to system grounding requirements.
- Use proper termination resistors for long-distance networks.
Performance Advantages
✔ Reliable differential signal transmission
✔ Strong EMI/RFI resistance

FAQ
Q1: What is the difference between RS485 cable and normal signal cable?
RS485 cables are designed with controlled impedance and shielding structures to maintain stable differential communication, while ordinary signal cables may suffer from higher interference and transmission loss.
Q2: Can this cable be used outdoors?
The standard version is mainly designed for indoor industrial applications. Outdoor installation may require additional protection such as conduit or customized weather-resistant jacket materials.
Q3: Why does RS485 require shielding?
RS485 networks often operate over long distances and in industrial environments where electromagnetic noise exists. Shielding helps reduce interference and improves communication reliability.
