Signal cables in drag chain systems fail too often — cracking insulation, signal interference, oil breakdown. Every downtime costs production. This 20-core 0.3mm² twisted pair shielded cable is engineered to survive continuous flexing, chemical exposure, and electrical noise in demanding machine environments.Product OverviewThis imported shielded control cable features 20 individually twisted pairs in 0.3mm² (22AWG) fine strand construction. Each pair is shielded to block EMI/RFI interference common near servo drives and VFDs. The outer jacket is oil-resistant and rated for millions of cycles in cable carriers and drag chains. It delivers reliable signal transmission where standard PVC cables crack or degrade within months.Core Specifications

Why This Cable Outperforms Standard Control WireDrag chain endurance. Tested beyond 10 million flex cycles at rated bend radius. The fine strand conductor and PUR jacket absorb repeated stress without conductor fatigue or jacket splitting — the two failure modes that kill ordinary cables in carriers.Oil and coolant resistance. PUR jacket resists hydraulic oil, cutting fluid, and lubricant splashes. Unlike PVC jackets that swell and crack on contact, this cable maintains flexibility and insulation integrity in CNC machining centers and stamping presses.Shielded signal integrity. Twisted pair geometry plus braid-and-foil dual shielding keeps crosstalk below -40dB and blocks EMI from nearby servo motors. Signal loss stays under spec even in high-noise automated assembly lines.Compact and lightweight. At roughly 8.5mm OD for 20 cores, it fits into small-profile drag chains and tight routing channels on robotic arms, pick-and-place machines, and gantry systems where space is limited.Applicable Industries & ScenariosCNC machine tools, industrial robots and robotic arms, automated assembly lines, packaging machinery, injection molding machines, laser cutting equipment, conveyor systems with moving cable carriers, semiconductor handling equipment.Service & CustomizationWe stock standard lengths from 1m to 500m with same-day dispatch.
