Cables in drag chain systems crack, signal noise kills sensor accuracy, and unplanned downtime eats into your output. When standard PVC wires fail after a few thousand bend cycles, you need a cable built for continuous motion — not just occasional use.This imported Japanese 4-core 0.5mm² (20AWG) shielded twisted pair cable is purpose-built for drag chain and cable carrier applications in robot control systems. Tinned copper conductors with polyester insulation survive tight bend radii. An overall tinned copper braid shield blocks EMI and RFI from servo drives, welders, and VFDs. The PUR jacket resists oil, coolant, and abrasion — the three things that destroy ordinary cables on the factory floor first.Core Parameters

What Makes This Cable Different Under Real Machine Conditions
- Tested beyond 10 million bend cycles. The tinned copper stranding and PUR jacket maintain flexibility inside high-speed drag chains on 6-axis robots and CNC machines — PVC jackets go brittle within months under the same motion.
- 85% braid coverage stops EMI where it matters. In welding cells and servo-driven robot arms, electromagnetic noise corrupts encoder feedback and sensor signals. This shield keeps signal integrity stable over 50+ meter runs without repeaters.
- PUR jacket handles real shop-floor chemistry. Resists hydraulic oil, cutting fluid, metal shavings, and mild solvents. Tested per DIN EN ISO 1817 — no swelling, no cracking, no jacket separation after 72-hour immersion.
- Low weight protects your drag chain. At ~35 kg/km, this cable adds minimal load to moving carriers. Heavier cables accelerate chain wear and reduce positioning speed on fast pick-and-place units.
