Cable failure inside drag chains is one of the top causes of unplanned downtime in robotic automation. Repeated bending cracks standard jacketing, hydraulic oil degrades insulation, and EMI from servo motors corrupts sensor signals — all leading to frequent replacements and costly production stops.This 4-core 0.2mm² PUR imported cable is engineered specifically for continuous flexing inside cable chain systems. The polyurethane (PUR) outer jacket resists cutting oils, hydraulic fluids, and coolant splashes common on factory floors. Tinned copper braiding shields each conductor pair against electromagnetic interference. The cable maintains signal integrity even after millions of flex cycles in tight-radius cable carriers.Core Parameters

Why This Cable Performs Where Others Fail
- PUR jacket outlasts PVC in oil-heavy environments. Standard PVC swells and cracks within weeks when exposed to machine oil or hydraulic fluid. PUR resists abrasion, oil, and microbe growth — typical service life exceeds 24 months in continuous oil mist conditions.
- Rated for tight-radius cable carriers. At 0.2mm² stranding, this cable flexes reliably in carriers with bend radii as low as 7.5mm. No conductor breakage after 10 million cycles in lab testing — critical for 6-axis robots and pick-and-place arms with compact chain loops.
- Copper braid shield blocks servo motor EMI. In robotic cells with multiple servo drives running simultaneously, unshielded cables pick up noise that triggers false sensor readings. The braid shield keeps signal-to-noise ratio clean for encoder feedback, proximity sensors, and I/O lines.
- Imported material, consistent quality batch to batch. Tinned copper prevents oxidation in humid or chemically aggressive workshops. Wall thickness and shielding coverage are held within ±5% tolerance — no weak spots that fail early in the chain.
