Structural Design & Signal Benefits
- Structural Design: 24 AWG stranded (7×32) tinned copper conductors, high-performance insulation, 2 independent twisted pairs with 100% coverage individual shielding, dedicated 24 AWG stranded tinned copper drain wire per pair, integral PVC outer jacket.
- Signal Benefits: Supports dual-purpose transmission of RS-232/422 serial signals and digital audio signals without mutual interference; low loss and high signal integrity for short-to-medium distance transmission; excellent anti-EMI/RFI capability; flexible and easy to wire; durable and long service life.
Installation & Performance Considerations
- Installation Notes: Conduct pre-installation inspection; comply with bending radius (8×OD static, 12×OD dynamic); max pulling tension ≤160N; keep 20cm away from high-power cables; terminate 2 pairs correctly, single-point grounding for each drain wire; indoor use only (-15℃~+65℃).
- Performance Notes: Operate within 250V rated voltage and 24 AWG ampacity; control transmission distance by signal type; ensure impedance matching; maintain shielding/grounding integrity; avoid high-noise environments and regular maintenance.
