TEBAOFLEX Li12YC11Y-JZ (also supplied in PVC-insulated YSLCY11Y-JZ builds) is an all-weather, inner-sheathed 300/500 V copper-braided EMC control cable adapted to EN 50525-2-51. By placing an extruded elastomer inner bedding sheath between fine-stranded Class 5 conductors and the concentric copper wire braid, and armouring the exterior with a notch-, oil-, hydrolysis-, and UV-resistant Silver Grey (RAL 7001) 11YM1 PUR sheath, it maintains noise-free signal and valve control from -40°C to +90°C flexing (-50°C fixed).
1. Application Scope & PUR Control Cable Selection Matrix
Standard PVC-sheathed YSLCY-JZ control cables stiffen in cold weather, swell in ester machining fluids, and tear easily against metal swarf. Upgrading to an inner-sheathed Li12YC11Y-JZ / YSLCY11Y-JZ polyurethane control cable provides full 360° braided electromagnetic compatibility alongside harsh-environment mechanical and chemical durability.
- CNC Machine Tools, Grinding & Transfer Lines: Proportional hydraulic valve, PLC I/O, limit-switch, and spindle sensor interconnects drenched in cutting emulsions, mineral oils, and metal chips.
- All-Weather Outdoor, Construction & Agricultural Machinery: Mobile cranes, concrete batching plants, timber harvesters, and port yard equipment exposed to UV sunlight, ozone, mud, and sub-zero
-40°Ccold flexing. - Food, Washdown & Cold-Storage Automation: Hydrolysis- and microbe-resistant ether-grade PUR jacket withstands damp washdown zones and freezer-warehouse conveyors without plasticizer leaching.

TPE Halogen-Free vs PVC-Core Supply Options: Our standard all-weather Li12YC11Y-JZ build uses 100% halogen-free TPE core and inner-sheath compounds for -40°C to +90°C flexing. Where customer BOMs specify conventional PVC-insulated YSLCY11Y-JZ (-5°C to +70°C flexing, -40°C fixed), TEBAOFLEX manufactures that exact construction to order.

5. Frequently Asked Questions (Shielded TPE/PVC-PUR Control Cable)
What is the structural difference between Li12YC11Y-JZ and YSLCY11Y-JZ screened PUR control cables?
Both constructions combine Class 5 fine-stranded bare copper conductors, black white-numbered cores with a green/yellow earth (-JZ), a concentric copper wire EMC braid (C), and an oil-resistant 11YM1 polyurethane (PUR) outer sheath. Li12YC11Y-JZ uses 100% halogen-free thermoplastic elastomer (TPE / 12Y) core insulation and an extruded TPE inner sheath to achieve a wider -40°C to +90°C flexing range, whereas YSLCY11Y-JZ uses flexible PVC core insulation (-5°C to +70°C/+80°C flexing) for standard indoor machine-tool wiring.
Why does this cable include an extruded inner bedding sheath beneath the copper wire braid?
Unlike foil-taped economy control cables, the extruded elastomer inner sheath fills the valleys between stranded cores and provides a smooth cylindrical cushion beneath the braided copper screen. That prevents copper braid wires from cutting into core insulation during repeated flexing, maintains 360° roundness inside IP68 EMC cable glands, and raises core-to-core test voltage stability to 4,000 V AC.
Can Li12YC11Y-JZ be used outdoors and in sub-zero cold-storage automation?
Yes. The UV-stabilized, hydrolysis- and microbe-resistant 11YM1 PUR outer sheath combined with low-temperature TPE core/inner-sheath compounds remains supple down to -40°C in flexing service and -50°C in fixed routing, making it suitable for mobile construction machinery, agricultural implements, wind-turbine nacelles, and cold-store conveyors.
When should I upgrade from Class 5 Li12YC11Y-JZ (15 × OD) to a Class 6 robotic drag-chain PUR cable?
Li12YC11Y-JZ (Class 5 conductor, 15 × OD flexing radius) is engineered for machine-tool harnesses, occasional/medium-cycle linear drag chains, and vibrating equipment. For high-acceleration, multi-million-cycle tight-radius energy chains (7.5 × OD) or robotic dress packs, specify our Class 6 Y11Y-JZ 600V PUR Robotic Drag-Chain Control Cable.
