PUR Shielded Drag Chain Cable (High-Flex, EMC Optimized)
Engineered for continuous reciprocating motion in demanding industrial environments, our PUR shielded drag chain cable delivers exceptional reliability where frequent bending, torsion, and electromagnetic interference are critical challenges. The halogen-free, hydrolysis-resistant PUR jacket combined with an enhanced shielding system makes this cable ideal for modern cable carrier systems, robotics, and automated machinery operating in tough indoor and outdoor conditions.
Key Features & Performance Advantages
- Halogen-free & environmentally robust: resistant to hydrolysis, microbes, oils, coolants, ozone, UV, weathering, acids, alkalis, and solvents
- Exceptional mechanical strength: high abrasion resistance, notch resistance, and capacity to withstand heavy mechanical loads
- Superior flexing and torsion resistance: optimized for continuous flexing, twisting, and high cycling rates in drag chain applications
- Excellent EMC performance: tinned copper braid shield with ≥85% coverage effectively suppresses electromagnetic interference
- Wide temperature range: suitable for fixed installations down to -45°C and flexing applications down to -35°C, up to +90°C
- Long service life: bending life exceeding 6 million cycles at 45 strokes per minute
Recommended Applications
This shielded PUR drag chain cable is designed for installation in cable carriers subjected to continuous reciprocating motion, especially where frequent flexing and tight bend radii are essential. Typical application areas include:
- Logistics systems, control systems, and mechanical automation systems
- CNC machine tools, electronic assembly equipment, metal stamping presses
- Wood, stone, glass, and window/door processing machinery
- Injection molding machines, robotic arms, and pick-and-place units
- Construction machinery, heavy machine building, automotive production lines
- Lifting and transport equipment, automated warehouses, docks, and fire trucks
- Indoor and outdoor locations requiring shielded cables under heavy mechanical load, including coastal, port, and field installations exposed to extreme temperatures and high contamination
