Structural Design & Signal Benefits
- Conductor: 22 AWG stranded (7×30) tinned copper for improved conductivity
- Insulation: Semi-rigid PVC ensuring electrical consistency
- Configuration: 2 twisted pairs for balanced signal transmission
- Shielding: Overall tinned copper braid for effective EMI/RFI protection
- Jacket: Flexible PVC sheath for durability and easy installation
- Larger conductor size (22 AWG) reduces signal attenuation
- Twisted pair structure enhances noise rejection
- Braided shielding provides strong protection against external interference
- Stable signal transmission for RS-232 applications
- Excellent flexibility for tight installation environments
Installation & Performance Considerations
- Keep proper bending radius to avoid internal conductor damage
- Maintain separation from power cables to minimize interference
- Ensure correct grounding of shielding layer for optimal performance
- Suitable for indoor installations and controlled industrial environments
- Operating temperature range: -20°C to +75°C
- Recommended for short to medium transmission distances per RS-232 standards
Proper installation ensures consistent communication performance and extended service life.
