Packaging can be customized based on project or distributor requirements.
Structural Design & Signal Benefits
- Conductors: 24 AWG stranded (7×32) tinned copper for flexibility and durability
- Insulation: Semi-rigid PVC ensuring uniform electrical properties
- Pairing: 25 twisted pairs for organized multi-channel transmission
- Shielding: Overall tinned copper braid for robust EMI protection
- Outer Jacket: PVC sheath offering mechanical strength and abrasion resistance
- Supports stable low-frequency signal transmission across multiple channels
- High shielding coverage reduces external noise interference
- Optimized pair structure minimizes internal crosstalk
- Tinned copper enhances oxidation resistance and long-term reliability
- Flexible construction simplifies routing in dense installations
Installation & Performance Considerations
- Maintain proper bending radius to preserve cable structure
- Avoid parallel installation with power cables to reduce interference risks
- Ground the shielding layer correctly for maximum performance
- Suitable for fixed installation in industrial and commercial environments
- Recommended operating temperature: -20°C to +75°C
- Ensure transmission distance aligns with RS-232 standards
Careful installation will significantly enhance signal stability and service life.
