Drag Chain Ethernet Cable

Flexible Network Cables for Cable Carriers and Moving Applications

Widely deployed in industrial automation systems that demand high-speed, high-accuracy data transmission and power supply under constant reciprocating motion: six-axis robotic arms, collaborative robots (cobots), gantry-type milling and engraving machines, CNC machining centers (where oil resistance, thermal endurance, and real-time signal integrity are critical), as well as automated assembly lines, logistics conveyors and sortation systems, industrial sensor networks, and smart surveillance installations.

Engineered specifically for drag chain and cable carrier systems, these high-flex Ethernet cables deliver exceptional mechanical endurance. Top-tier versions consistently achieve 10 million bending cycles. Strong electromagnetic immunity is provided by an aluminum foil wrap + tinned copper braid shield, effectively suppressing interference from motors, VFDs, and other industrial noise sources to keep signal transmission stable. The cable construction also offers high tensile and compressive strength, absorbing mechanical stress inside the drag chain while preserving electrical and mechanical performance under pulling forces.

Frequently Asked Questions

Can I combine power cores and data pairs in the same drag chain cable?
Yes. We can manufacture hybrid cables that integrate shielded Ethernet pairs with control conductors and power cores – all within a single, highly flexible PUR or NBR jacket. This simplifies cable management in multi-axis robots and moving machine heads. Contact our engineering team with your conductor count and rating.

What shielding configuration do you recommend for heavy VFD environments?
For high-EMI areas near motor drives and welding equipment, we specify aluminum foil plus high-coverage tinned copper braid (SF/UTP or S/FTP). This double-layer shield handles both low- and high-frequency noise. If you need continuous flexing with an industrial RJ45 connector system, we can advise compatible screened cable assemblies.

Do you supply the cable with pre-assembled connectors and tested link lengths?
Yes, we offer ready-to-install assemblies with overmolded or field-attachable RJ45, M12 D-coded/X-coded, and push-pull connectors. Every assembly is 100% tested for wiremap, return loss, and NEXT. Lead times and minimum order quantities depend on connector type and length – please request a quotation.

What is the difference between NBR and PUR jackets in drag chain applications?
NBR (nitrile) offers very good oil resistance and flexibility at a cost-effective price, suitable for standard machinery. PUR (polyurethane) provides superior abrasion, cut resistance, and long-term flex performance, recommended for high-cycling carriers and contact with chips or spark exposure. We help you select based on your installation environment and required lifespan.

Can I get custom cable marking, cable diameters, or special colors?
Absolutely. We can print your company’s part number, length markings, and specific color codes on the jacket. Custom outer diameters, ultra-flexible stranded conductors, and low-friction surface finishes are also available for OEM projects.
