Machine tool cables fail fast in oily, high-vibration environments. Standard PVC jackets crack, copper conductors oxidize, and signal interference creeps into data lines — costing you unplanned downtime and replacement cycles measured in months, not years.The ONAMBA Japan 4-core 2mm² cable is built for exactly these conditions. Tin-plated copper conductors resist oxidation and maintain stable conductivity even in coolant-splash zones. The oil-resistant outer jacket handles cutting fluids, hydraulic oil, and industrial grease without swelling or hardening. Four cores give you the flexibility to run power and control signals in a single cable run — one less wire bundle cluttering your machine enclosure.Core Specifications

Why This Cable Holds Up Where Others Don’tTin plating on every copper strand — not just the surface. In CNC machining centers where cutting mist and coolant sit on cable trays 24/7, bare copper turns green within weeks. Tin-plated conductors stay clean, resistance stays low, and you avoid the intermittent faults that plague motor drive signals.Oil-resistant jacket tested to ISO 1817 immersion method. Swelling under 3% after 72 hours in IRM 902 oil. That means the jacket keeps its grip on connectors, doesn’t get sticky, and won’t crack when the machine arm swings past it thousands of times a shift.Four-core layout separates power and signal intentionally. Two cores handle motor or heater power, the other two carry encoder feedback or sensor data. Shared jacket, separate function — reduces conduit fill by up to 40% compared to running two separate cables.Flexible Class 5 stranding survives constant drag-chain movement. Tested to 10 million cycles in reciprocating cable carrier applications. No conductor breakage, no jacket fatigue at the flex point.Applicable Industries & Use CasesCNC lathes and milling centers — motor power leads and encoder feed cables. Servo and stepper motor wiring in automation cells. Industrial robot teach pendant and signal cables. Packaging machines, injection molding units, and conveyor systems where oil and vibration are constant. Also suitable for power distribution inside electrical cabinets and machine tool pendants.Sourcing, Customization & SupportWe stock standard lengths from ONAMBA Japan with 2–3 week lead time on bulk orders.
