Structural Design & Signal Benefits
- Conductor: 22 AWG stranded (7×30) tinned copper for enhanced conductivity and flexibility
- Insulation: Semi-rigid PVC ensuring stable dielectric performance
- Configuration: 3 twisted pairs for structured signal grouping
- Shielding: Overall tinned copper braid to protect against EMI/RFI
- Jacket: PVC outer sheath providing mechanical protection and durability
- Low signal attenuation for reliable data transmission up to 15 meters at standard baud rates
- Excellent impedance matching reduces signal reflections
- Superior EMI/RFI rejection ensures error-free communication in electrically noisy environments
- Stable performance across a wide temperature range (-20°C to +70°C)
Installation & Performance Considerations
- Observe recommended bending radius to maintain cable integrity
- Avoid routing alongside high-voltage or high-frequency cables
- Proper grounding of the braid shield is essential for noise suppression
- Suitable for indoor and light industrial installations
- Operating temperature range: -20°C to +75°C
- Best suited for short to medium distance RS-232 communication
Correct installation practices will help maximize performance and lifespan.
