Zhejiang Chatnow New Material Technology Co., Ltd. is one of the leading manufacturers and suppliers of rs485 overall shielded 7×2×24awg communication cable in China. With abundant experience, we warmly welcome you to wholesale bulk high quality products at competitive price from our factory. We also accept customized orders.

APPLICATION
The cable adopts 7 twisted pairs (7Pr) 24AWG stranded tinned copper conductors, with Al/PET foil shielding + tinned copper braid shielding structure, providing excellent electromagnetic interference (EMI) protection and signal integrity.
The overall shield design effectively reduces external noise interference, ensuring stable communication performance in industrial automation, control systems, security systems, and intelligent equipment applications.
According to the specification, the cable uses Foam-PE insulation, PVC outer jacket, ≥65% tinned copper braid coverage, with operating temperature from -30℃ to +80℃ and RoHS compliance.
This RS485 communication cable is widely used in:
Industrial Automation

2. Cable Routing
Avoid installation parallel to:
- High voltage cables
- Motor power lines
- Strong electromagnetic interference sources
3. Bending Radius
Avoid excessive bending during installation to maintain:
- Pair geometry
- Impedance stability
- Shield integrity
4. Temperature Range
Recommended operating environment:
-30℃ ~ +80℃

FAQ
Q1: Is this cable suitable for RS485 communication?
A: Yes. The cable is specifically designed for RS485/RS422 differential communication applications with twisted pairs and shielding structure.
Q2: Why use tinned copper conductors?
A: Tinned copper provides better corrosion resistance and long-term stability compared with bare copper, especially in industrial environments.
Q3: What is the advantage of double shielding?
A: Aluminum foil protects against high-frequency interference, while copper braid provides additional grounding and low-frequency EMI protection.
Q4: Is it RoHS compliant?
A: Yes. The cable complies with RoHS environmental requirements.
