Robot cables in cable chains fail too often — insulation cracks, shielding wears through, and signal interference shows up mid-production. Downtime from replacing dragged cables eats into every shift. What you need is a cable built for millions of bending cycles, not thousands.This is the DYDEN 6-core 0.75 sq mm shielded cable — imported from Japan, engineered specifically for robot power cords and continuous flex in cable chains and drag chains. It handles tight bend radii, resists oil and abrasion, and keeps EMI out of your sensor and servo signals. No over-engineering. No generic wire. Just a cable that survives real machine motion.Core Specifications

Why This Cable Outlasts Standard Robot Cords
- 10M+ flex cycles in drag chains. The stranded tinned copper and PUR jacket combination absorbs repeated motion without conductor fatigue. Tested on 15mm bend radius at 1.5m/s — no insulation cracking after 10 million strokes.
- Braided shield stays intact under flex. Most shielded cables lose grounding when bent repeatedly. DYDEN uses a tinned copper braid bonded to the jacket, so shielding coverage holds even after years in energy chains. Your encoder and sensor signals stay clean.
- PUR jacket resists machine oil, coolant, and abrasion. CNC machines, welding robots, and palletizers splash oil constantly. PUR outperforms PVC in oil resistance and does not harden or crack at low temperatures — critical for cold storage or outdoor robotic cells.
- Compact OD fits tight cable chains. At 0.75 sq mm per core with 6 conductors, the overall diameter stays under 11mm. Fits standard 15×15mm and 18×25mm energy chains without forcing the chain open or adding excess weight to moving axes.
Suitable Industries & ApplicationsIndustrial robots (6-axis, SCARA, delta) — power and signal routing through wrist and base cable chains. CNC machines and machining centers — tool changer and axis drag chains. Servo motor connections on moving gantries and pick-and-place systems. Welding robots — high-flex segments near the torch arm. Automated guided vehicles (AGVs) — power feed through tow chain. Packaging and palletizing lines — continuous motion cable carriers.Service & CustomizationWe stock DYDEN 6-core 0.75 sq mm in standard lengths.
