2-Core 0.3mm² Shielded Drag Chain Cable – High Flex

Unexpected cable breaks inside an energy chain don’t announce themselves. A single interrupted conductor can stop an automated line for hours. The 2-core 0.3mm² shielded drag chain cable is built to remove that variable. It pairs fine-stranded copper conductors with a dense braided shield, sustaining millions of flex cycles without signal drop. This translates directly into longer maintenance intervals and a measurable reduction in unplanned downtime.

Why this cable outperforms standard control lines

Stranding engineered for continuous motion

Ultra-fine bare copper strands, laid in short pitch lengths, distribute mechanical stress evenly across every flex cycle.
Standard hook-up wire fatigues early at the bend point. This design delays the onset of copper work-hardening, so the cable keeps its conductivity long after generic alternatives have cracked. The practical outcome: you replace cables less often and keep production capacity intact.

Braided shield that actually protects the signal

A tinned copper braid with coverage above 85% encloses the two cores, maintaining a consistent low-resistance path to ground.
EMI and crosstalk from adjacent power cables or VFD-driven motors stay out of the measurement loop. For servo feedback, encoder data, or sensor signals, that means no corrupted pulses leading to positional drift or false stops.

Jacket compound matched to industrial environments

A halogen-free PUR outer sheath resists mineral oils, synthetic coolants, and repetitive abrasion inside the chain.
Even when the cable slides against chip-laden plastic separators or operates under light oil spray, the jacket surface remains intact. No swelling, no embrittlement, no sudden insulation failure that forces a line shutdown.

Tight bending radius without performance loss

A flexing bend radius down to 7.5 × outer diameter allows installation in compact cable carriers and articulated robot arms.
Machine designers gain envelope space, and maintenance teams benefit from hassle-free retrofits into existing cable guidance systems without re-engineering the carrier layout.

Pre-assembled and tested options reduce your onsite work

This cable can be supplied cut-to-length with overmoulded connectors, continuity-tested and labelled.
You receive a ready-to-install harness that eliminates stripping errors, cold solder joints, and QC bottlenecks inside your own assembly shop — and you only pay for what you need.

Technical specifications

Where this cable removes real operating risk

• Robotic articulated arms
  Withstands multi-axis torsion and continuous flexing in the robot’s dress pack without conductor fatigue, even under rapid axis reversals.

• Linear actuators and pick-and-place units
  Rejects electromagnetic noise from adjacent servo drives, keeping position feedback accurate during high-speed indexing.

• Packaging and filling machinery
  Resists incidental contact with vegetable oils, cleaning agents, and light mechanical impact on fast-moving carriages.

• CNC machine tools and grinders
  Operates reliably inside cable chains exposed to fine metal chips and coolant mist, where unshielded cables pick up switching noise that causes flagging errors.

• Measurement and test benches
  Preserves microvolt-range signals over long travel distances by suppressing both conducted and radiated interference — critical for strain gauge or thermocouple instrumentation.

Questions procurement engineers ask before specifying

Can you supply a long-term flex cycle test report for this exact configuration?
Yes. We provide test data generated under defined conditions (stroke length, acceleration, bend radius) on identical 0.3mm² constructions. The report includes electrical continuity monitoring and jacket wear assessment. It removes guesswork when calculating service intervals for your specific axis geometry.

Is the shield resistance consistent after millions of cycles?
The braid is applied with an optimised lay angle and kept shorter in pitch than the core assembly. This reduces relative strand movement during bending. Measured DC resistance from connector to connector typically deviates less than 8% over the tested flex life. We recommend a 360° EMC cable gland connection to preserve that low-impedance path.

What’s the real lead time for cut-to-length orders with connectors overmoulded?
Standard lengths without connectors ship from buffer stock within 5–7 working days EU-wide. Overmoulded assemblies of this cable are built against purchase orders. Depending on complexity and testing requirements, expect 15–20 working days from drawing approval. Express service is available for urgent retrofit projects — contact with the final axis sketch and cycle profile.
