Robotic Arm Shielded Cable

High-Flex, Torsion-Resistant Cable for Robots & Automated Systems

Our robotic arm shielded cable is an engineered upgrade over standard flexible moving cables, purpose-built for continuous torsion, high-speed travel, and extreme flex cycles. It combines exceptional oil, abrasion, UV, and chemical resistance with reliable operation in ambient temperatures from -20°C to +80°C. The cable delivers a service life exceeding 6 million flex cycles (test data: 7 million cycles) and withstands instantaneous torsional speeds up to 2 m/s (test data: 3 m/s). This makes it a dependable choice for drag-chain manipulator linkages, multi-axis robot systems, and industrial automation equipment where nonstop motion and dynamic torsion are everyday demands.

Key Performance Characteristics

Torsion & flex endurance – survives millions of twisting and bending cycles without degradation
High-speed motion – rated for instantaneous movement up to 2 m/s
Oil & chemical resistance – jacket compounds resist cutting fluids, hydraulic oils, and mild acids/alkalis
UV & weather resistant – prevents jacket cracking in outdoor or exposed installations
Wide temperature range – performs consistently from -20°C to +80°C
Superior abrasion resistance – extended service life in drag chains and cable carriers

Applications

Articulated robotic arms and manipulator linkages
Drag-chain robot power and signal supply systems
Industrial robots, cobots, and pick-and-place units
Automated machinery with continuous torsion and reversing motion

Technical Specifications

Conductor
Fine stranded oxygen-free copper (OFC) for maximum flexibility and signal integrity.

Insulation
Special composite compound developed for high-flex signal cable applications.

Color Code
Conforms strictly to German VDE standards.

Shielding
Dual-layer shield design: aluminum foil/Mylar wrap plus tinned copper braid, each with ≥85% coverage. Superior EMI protection suitable for sensitive signal transmission in electrically noisy environments.

Drain Wire (optional)
Same cross-section as the conductors; simplifies shield termination and grounding during harness assembly.

Jacket

Standard: Special hybrid modified nitrile compound – excellent oil, abrasion, and flex performance
High-spec option: PUR polyurethane – superior mechanical toughness, cut resistance, and chemical resistance

Jacket Colors
Green (RAL 6018), Orange (RAL 2003), Purple (RAL 4001). Custom RAL colors available on request.

FAQ – Robotic Arm Shielded Cable

What torsional speed and cycle life can I realistically expect?
During normal motion, the cable handles instantaneous torsional speeds up to 2 m/s (tested to 3 m/s in laboratory conditions) and achieves over 6 million flex cycles (tested to 7 million). Actual life depends on bend radius, acceleration, and environment, but these numbers give a reliable design margin for high-duty robotic applications.

Which jacket material should I choose for oily or harsh environments?
Both our modified nitrile compound and PUR jackets offer strong oil and abrasion resistance. Nitrile is a cost-effective choice for most industrial robot cells. PUR polyurethane is recommended when you need superior cut resistance, exposure to aggressive chemicals, or outdoor UV stability. We can help you select the right compound based on your specific operating conditions.

Can I get this cable with custom colors and my company’s legend?
Absolutely. Standard colors are green, orange, and purple (per RAL codes). We will match any RAL color and print your custom legend on the jacket. Simply provide details with your inquiry.

Do you provide samples and test data before bulk procurement?
Yes. We strongly recommend real-world testing in your own machine setup. Contact us to request a free sample length, along with detailed test reports and specification sheets.

How is the shield constructed, and can you guarantee ≥85% coverage?
Our standard design uses an aluminum foil/Mylar wrap plus an overall tinned copper braid, each with coverage of 85% or higher. An optional drain wire eases termination. We can also engineer alternative shielding arrangements (e.g., single braid, high-coverage spiral, or combination shields) to match your EMC requirements—every design is verified before shipment.
