Encoder cables in oil-rich or high-vibration environments fail fast. Shielding degrades, insulation cracks, signal loss causes positioning errors — and unplanned downtime costs thousands per hour. The OKI Japan 4-core 0.5mm² twisted pair shielded encoder cable is built to survive exactly those conditions.This cable features individually shielded twisted pairs within an overall braided shield, paired with an oil-resistant PVC jacket and 20 AWG (0.5mm²) conductors. It delivers stable signal transmission even in CNC machine chains, servo motor feed lines, and robotic arm cable carriers — where constant flexing and hydraulic oil exposure are daily reality.

Why This Cable Outperforms Generic Alternatives
- Oil and chemical resistance that lasts. The jacket resists mineral oil, hydraulic fluid, and cutting coolant — no swelling or hardening after 6+ months in machine tool enclosures.
- Signal integrity under constant motion. Tight twist pitch plus dual shielding keeps crosstalk and EMI low even when the cable bends 5 million+ cycles in drag chains.
- Small OD, tight bend radius. At roughly 6.5mm outer diameter, it fits standard 10mm-wide cable carriers without forcing — critical on 6-axis robots and compact CNC turrets.
- OKI Japan quality, not re-branded imports. Consistent conductor resistance, uniform shielding coverage, and full traceability per reel — no batch-to-batch variation.
Typical Applications & Industries
- CNC machining centers and lathes (encoder feed lines, spindle signal)
- Servo motor and inverter connections
- Industrial robot arms and collaborative robots
- Packaging machines, printing presses, textile equipment
- Any application requiring oil-resistant, high-flex encoder cable in motion systems
