Structural Design & Signal Benefits
- Structural Design: 4-pair 24AWG (7×32) tinned copper conductors; precision insulation; 100% individual shielding per pair with dedicated drain wire; overall PVC jacket.
- Signal Benefits: 4 independent channels for simultaneous transmission without interference; strong anti-EMI/RFI; low signal attenuation; flexible installation; stable performance in commercial and light industrial environments.
Installation & Performance Considerations
- Installation: Indoor use only; bending radius ≥8×OD (fixed) / ≥12×OD (dynamic); separate from high-voltage cables; correct termination & grounding; matched connectors.
- Performance: RS-232 max distance 15m, RS-422 max 1219m; keep shielding intact; match transmission rate; regular inspection; single-point grounding.
