18 Core 1mm² PURO-JZ-HF Polyurethane Cable: Engineered for High-Flex Automation Systems

A single cable failure in a moving chain doesn’t just stop a motor. It halts entire production lines. The cost isn’t the replacement part. It’s the unplanned downtime, the scrapped batches, and the overtime needed to hit deliveries. On high-speed gantries, robotic arms, or drag chains exposed to coolants, the standard control cable degrades fast. Jacket cracks appear. Conductors snap. Premature failure becomes the accepted norm. This cable was designed to replace that norm with a calculated, long-life solution.

The PURO-JZ-HF 18x1mm² is a high-flex polyurethane-sheathed cable built specifically for continuous bending and torsion stress. The combination of finely stranded bare copper, a halogen-free polyurethane outer jacket, and a numbered core identification system solves two critical operational requirements: reliable signal and power transmission in constant motion, and compliance with evolving fire safety and cleanroom controls. No additives that generate corrosive gases. No PVC jacket that stiffens over time. Just predictable, documented longevity on the cable track.

Precision Stranding for Constant Flex Zones
[Feature]: 18 cores of 1.0mm² fine-wire bare copper, constructed to Class 5 IEC 60228 flexibility standards.
[Advantage]: The high strand count distributes bending stress across hundreds of individual filaments rather than concentrating it on a few rigid cross-sections. Core failure from work hardening is delayed significantly.
[Benefit]: Extended replacement intervals on multi-shift automated machinery. Maintenance teams move from reactive cable swaps to scheduled preventative inspections. Parts inventory shrinks.

Halogen-Free Polyurethane Outer Jacket
[Feature]: Proprietary halogen-free polyurethane compound, flame retardant to IEC 60332-1-2. Does not emit chlorine, fluorine, or bromine gases when exposed to flame.
[Advantage]: PU delivers 3 to 4 times the abrasion resistance of standard PVC compounds. The material resists mineral oils, synthetic cooling lubricants, and hydrolysis. Halogen-free formulation eliminates corrosive gas risk during a thermal event.
[Benefit]: One cable specification covers both the machine builder’s warranty requirements and the end-user’s fire safety protocols. No secondary protective conduit needed in coolant-flooded machining centers. Ventilation systems remain uncontaminated after a fire.

Continuous Flex & Torsion Rated
[Feature]: Multi-layer core stranding optimized for C-track and torsion applications. Tested beyond 5 million bend cycles at the minimum bend radius.
[Advantage]: Maintains signal integrity and conductor resistance stability across the entire rated flex life. No intermittent open circuits develop midway through the expected service cycle.
[Benefit]: Validated uptime on robotic seventh-axis slides and high-cycle pick-and-place units. Controls engineers gain the confidence to specify a known cycle-life component into their reliability calculations.

Oil-Resistant & Chemically Robust
[Feature]: Jacket resistance to mineral oil per EN 50363-10-2 and extended hydrolysis testing in 80°C water environments.
[Advantage]: No swelling, embrittlement, or delamination between the jacket and inner layers after prolonged chemical exposure. Core number prints remain legible.
[Benefit]: Universal deployment across wet machining, metal forming presses, and washdown areas without derating the service life. Procurement reduces approved vendor lists by standardizing on a single multi-environment cable.

Technical Specifications

Industry Applications & Validated Environments

• Automated Machine Tools & CNC Machining Centers: Routes power and signal to turrets, spindles, and tool changers through wet, oil-mist-laden drag chains. The PU jacket shrugs off hot chips that would melt PVC, while halogen-free chemistry protects sensitive in-cabinet electronics from corrosive gas exposure during any electrical fault.
• Robotic Arms & Seventh-Axis Transfers: Absorbs constant torsion and multi-axis bending at high acceleration rates. Fine-wire stranding prevents conductor fracture under the repeated start-stop cycles that cause rigid cables to work-harden and snap at the strain relief.
• Material Handling & Automated Warehousing: Connects sensors and drives on stacker cranes, shuttle cars, and sorting gantries operating 24/7. Extended flex life reduces the frequency of night-shift maintenance callouts and subsequent penalty clauses on system uptime guarantees.
• Renewable Energy Manufacturing: Installed on solar panel stringers and wind turbine component grinders where cleanroom-like cable combustion toxicity is specified. Meets the halogen-free requirements that are increasingly written into EU and North American green manufacturing facility standards.
• Food & Beverage Process Automation: Used on packaging lines and palletizers where frequent high-pressure washdowns occur. The non-porous jacket surface resists bacterial adhesion, and resistance to alkaline cleaning agents prevents jacket cracking common with standard industrial cables.

Frequently Asked Questions

What is the rated bending life of this 18-core cable in a drag chain application?
Cycle life depends on the bend radius, travel speed, and acceleration. At the minimum bend radius of 7.5 x cable diameter, this construction has been validated beyond 5 million continuous flex cycles in independent testing. For travel distances exceeding 10 meters and accelerations above 5 m/s², please contact our engineering department for a specific life projection. We can model the service life based on your machine’s travel geometry.

We need exactly 18 cores. Do you offer a shielded version for VFD signals in the same cable?
The standard PURO-JZ-HF is an unshielded control cable. For applications mixing motor power feedback and encoder signals, an 18-core unshielded cable may not provide sufficient noise immunity against common-mode currents. We recommend a separate shielded PUR cable for signal pairs combined with this 18×1.0mm² for power distribution. Alternatively, we can tool a hybrid shielded version for annual volume orders exceeding 5,000 meters. Contact us with your noise immunity requirements and motor parameters.

What does the black numbered core coding mean for our panel wiring time?
Each of the 18 cores is black and printed with a durable white Arabic number, 1 through 18. This continuous numbering eliminates the labor of ringing out or adding shrink labels to identically colored conductors. For European machine builders wiring to EN 60204-1, this scheme aligns with the standard numerical identification method, speeding up panel termination and reducing wiring faults on complex multi-axis machines. The print compound is chemically bonded to survive contact with cleaning solvents.

Does the halogen-free jacket perform as well as PVC in cold environments?
The flexibility of this specific PU compound at low temperatures differs from PVC. A standard PVC jacket stiffens significantly below 0°C. This material maintains mechanical integrity down to -5°C for dynamic flexing and -40°C for a static installation. If your cable is routed outside a heated enclosure into a -20°C warehouse environment, avoid flexing it while frozen. Once installed static, it continues to perform without jacket cracking. For dynamic flex below -5°C, request our low-temperature TPU variants.
