26-Core 0.1mm² PUR Drag Chain Cable | Oil Resistant

The moment a signal cable fails inside a cable carrier, your entire automated line stops. Not next month. Not next shift. Now. You might be looking at 20 minutes of downtime. Or 20 hours. The cost multiplier depends entirely on how deep in the harness the break is and how quickly your team can trace 26 identical black conductors through a greasy e-chain. This problem compounds fast when mineral oil from nearby gearboxes saturates a standard PVC jacket, turning it brittle long before the copper reaches its flex-cycle limit.

This 26-core 0.1mm² PUR drag chain cable is engineered specifically to remove that unpredictability from high-density control and signal circuits. By combining an oil-resistant polyurethane outer sheath with a finely stranded core design, it pushes mean time between failures far past conventional PVC alternatives in continuous-flex applications. Fewer unscheduled interventions. More predictable maintenance budgets. This is the math that matters.

PUR Jacket Durability Under Continuous Motion

Feature: Halogen-free polyurethane outer jacket with a Shore hardness of approximately 85-90 A.
Advantage: Inherent resistance to mineral oils, cooling lubricants, and cutting fluids that dominate metalworking and injection molding plants. PUR’s abrasion resistance far exceeds that of standard PVC compounds.
Benefit: Cable glides over itself and through carrier dividers without jacket thinning. Oil doesn’t penetrate and leach plasticizers out of the compound. You replace this cable because the machine’s lifecycle ends. Not because its jacket turned to cracked plastic.

High-Density 26-Core Configuration

Feature: 26 individually insulated conductors at 0.1mm² cross-section per core, bundled at the optimal lay length for continuous flex.
Advantage: Consolidates multiple signal channels, sensor feedback loops, and low-current control circuits into one compact tether. No need to stack multiple smaller cables, which tangle, twist, and chafe against each other inside the carrier.
Benefit: Saves tray space and reduces carrier weight. That matters on fast gantry robots and pick-and-place heads, where every 100 grams subtracted from a moving cable pack reduces cycle time and drive motor wear over 5 million annual strokes.

Fine-Stranded Bare Copper Conductors

Feature: Stranded bare copper, conforming to IEC 60228 Class 6 flexible conductor construction.
Advantage: Maximum flexibility without the work-hardening fractures common in semi-rigid conductors. Class 6 stranding spreads bending stress evenly across a higher count of individual filaments.
Benefit: Consistent signal transmission integrity through millions of small-radius flex cycles. A fractured conductor inside a 26-core bundle is a diagnosis nightmare. This stranding specification pushes that failure point far beyond your scheduled preventive maintenance interval.

Oil-Resistant Signal Integrity

Feature: Core insulation and outer jacket designed to resist mineral oil per EN 60811-404 test conditions.
Advantage: Oil ingress doesn’t swell the insulation or cause core-to-core capacitance shifts that corrupt low-voltage signals from thermocouples, encoders, and proximity sensors.
Benefit: The control system reads clean data. No phantom position errors. No mystery e-stop events traced back to a sensor cable reporting falsely. In a 26-wire harness, one drifting signal is enough to halt production while diagnostics run.

Tight Minimum Bend Radius

Feature: Designed for a bending radius as low as 7.5 x outer diameter in continuous flex applications.
Advantage: Follows the tight arcs of compact drag chains on 3-axis CNC routers, automated guided vehicles, and linear actuator stages with short stroke lengths.
Benefit: Machine designers don’t need to oversize carriers to accommodate cable stiffness. Tighter bends mean smaller machine footprints. Floor space isn’t free.

Industry Applications & Scenario Validation

• CNC Machining Centers: Lubricant and cutting fluid resistance means this cable runs reliably for years inside splash-exposed drag chains feeding tool turrets and coolant nozzles with control signals.
• Injection Molding Automation: Side-entry robots and sprue pickers operating in hydraulic oil mist environments degrade standard cables within months. The PUR jacket eliminates that vulnerability at the material level.
• High-Speed Pick-and-Place Systems: The 26-core configuration consolidates vacuum sensor, gripper confirm, and presence-detect signals into a single lightweight cable, cutting moving mass in the fastest robot axes.
• Automated Test Equipment (ATE): High-density connections with consistent inter-core capacitance allow clean transmission of low-voltage measurement signals across a moving test head without cross-talk induced false readings.
• Linear Actuator Stages: Small cross-section plus PUR toughness suit the narrow, tight-bend carriers common in laboratory automation, semiconductor wafer handling, and precision dispensing systems.

FAQ

Can this 26-core cable carry power to small motors and sensors simultaneously?
It’s rated for signal and low-current control circuits, not powertrain loads. At 0.1mm² per core, the maximum current per conductor sits in the range of 0.5-1A depending on ambient temperature and bundling. Pushing higher loads across multiple paralleled cores is possible only after a careful voltage-drop calculation and confirmation of insulation temperature class with our engineering team. For applications mixing moderate power and signals, ask about our hybrid configurations.

How do you distinguish 26 identical cores during termination?
Every core carries a unique number printed at regular intervals along its insulation length. The print is durable and legible even after extended oil exposure. The numbering scheme follows the standard color-plus-number system per HD 308 identification. This removes guesswork for your panel-building team and speeds up field repairs.

We require a specific lay length to avoid corkscrew failure in our carrier geometry. Is this configurable?
Yes. The lay length of the stranded cores relative to the bend radius of your drag chain directly determines service life. If your application involves unusual carrier lengths or rapid oscillation, we adjust the bunch stranding and overall cabling lay to match your kinematic profile. Provide the chain type, travel distance, and acceleration; our engineers return a lay configuration calculated for that motion curve, not a generic medium-flex compromise.

Request Load-Cycle Data for Your Machine Parameters

A cable works until it doesn’t. The question is when. Tell us your carrier’s travel length, bend radius, acceleration, and cycle count per day. We’ll return a verified flex-life estimate based on bench-test data—not a generic sales promise.
