Amidst the Industry 4.0 wave, IO-LINK—as the core protocol for underlying device networking—demands increasingly stringent requirements for connection stability, interference resistance, and adaptability.
Our company, specializing in industrial connectivity technology, has developed dedicated M5/M8/M12 IO-LINK cables and M12 to RJ45 conversion cables. Centered on ‘high reliability, full-scenario adaptability, and simplified cabling,’ these products provide seamless connectivity solutions from sensors/actuators to master stations, completely resolving the pain points of traditional cabling: multiple interference, difficult compatibility, and cumbersome maintenance.
Addressing the industrial environment's characteristics of "varying equipment sizes, diverse installation spaces, and complex, dynamic conditions," we offer three key connector sizes—M5, M8, and M12—covering full-scenario connectivity needs from miniature sensors to heavy-duty actuators. Each cable strictly adheres to the IEC 61131-9 IO-LINK standard, ensuring perfect compatibility with mainstream master/slave stations.
Core Advantage: Utilizes an ultra-compact M5 threaded connector (diameter just 5mm), ideal for micro photoelectric sensors and pressure sensors with limited installation space.
Performance Guarantee: 4-core shielded twisted pair design (conductor cross-section 0.14mm²), supporting transmission distances up to 10 meters.
Suitable Applications: Micro-sensors in 3C electronics assembly lines, precision detection modules for medical equipment.
Core Advantage: 8mm standard threaded interface balancing compactness and universality; supports full IO-Link V1.1/V1.2 protocol versions.
Performance Guarantee: 0.25mm² conductor cross-section delivers 2A power supply.
Environmental Adaptability: Oil-resistant PVC material with -20°C to 80°C temperature tolerance.
Suitable Applications: Automotive component production lines, food packaging machinery, and logistics sorting lines.
Core Advantage: 12mm heavy-duty threaded connectors, supports dual-function ‘signal + power’ transmission in a single cable, reducing cabling costs by 50%.
Superior EMC: Dual-layer shielding (tin-plated copper mesh + aluminum foil) enhances interference resistance by 60%.
Dynamic Use: Optional PUR material offers high bend resistance, exceeding 1 million bending cycles.
Applications: Heavy-duty machine tools, metallurgical equipment, robotic arms.
| Feature | M5 IO-LINK Cable (Micro) | M8 IO-LINK Cable (Universal) | M12 IO-LINK Cable (Heavy-Duty) |
| Core Application | Miniature Devices, Confined Spaces | Standard Sensors & Small Actuators | Heavy Machinery, Dynamic/Harsh Environments |
| Connector Size | Ultra-Compact (5mm) | Standard (8mm) | Robust (12mm) - A/D Coded |
| Conductor Size / Power | 0.14mm² (Signal) | 0.25mm² / 2A Power Supply | 0.5mm² / Integrated Signal + Power |
| Max Distance (Typical) | 10 meters | Standard IO-LINK range | 20 meters (IEC Compliant) |
| Shielding/Design | 4-Core Shielded Twisted Pair (>95% coverage) | Oil-Resistant PVC Insulation | Dual-Layer Shielding (Mesh + Foil) |
| Key Benefit | Resolves "cannot fit" issues in 3C/Medical | Cost-effective, Universal compatibility | 1 Million+ Bending Cycles (PUR Option) |
In IO-LINK systems, certain masters (e.g., industrial PCs) utilize RJ45 Ethernet interfaces, whilst slaves predominantly employ M12 connectors. Our M12 to RJ45 IO-LINK conversion cable enables direct 'M12 slave → RJ45 master' connectivity without intermediate protocol converters, simplifying topology and ensuring communication stability.
Plug-and-Play Simplicity: Pre-terminated M12 D-coded (IO-LINK specific) and RJ45 Cat5e interfaces reduce commissioning time by 80%.
Signal Integrity: Utilizes Cat5e shielded twisted pair cable supporting 100Mbps transmission rates. Meets dual IO-LINK and Ethernet signal requirements up to 100-meter transmission distance (RJ45 end).
Industrial-Grade Protection: Connectors feature IP67 ingress protection and cable insulation employs flame-retardant PVC compliant with UL94 V-0 standards.
Broad Compatibility: Compatible with IO-LINK masters from leading brands including Siemens, Beckhoff, and Rockwell.
We prioritize ‘industrial-grade reliability’ throughout the entire supply chain, ensuring comprehensive quality assurance across all M5, M8, and M12 product lines:
Superior Interference Resistance: All cables feature ‘shielded twisted pair + tin-plated copper mesh shielding’ design, effectively mitigating strong electromagnetic interference, resulting in communication error rates below 0.001%.
Wide Environmental Adaptability: Temperature tolerance spans -40°C to 105°C (PUR variants), with resistance to oil, acids, alkalis, and ageing.
Convenient Installation & Maintenance: Connectors feature foolproof designs (e.g., D-coding) to prevent misinsertion. Clear surface markings enable rapid identification during maintenance.
Extended Service Life: Exceeding 1 million cycles for dynamic bending applications (cable chains), representing 2-3 times the lifespan of conventional cables, thereby reducing equipment replacement costs.
Our dedicated IO-LINK solutions offer a compelling value proposition for optimizing your automated systems:
Precision-Tailored: Comprehensive coverage of M5/M8/M12 specifications, custom-engineered for specific scenarios.
Enhanced Cost Efficiency: Single-cable transmission of both signal and power reduces cable usage by 50%. M12-to-RJ45 cables eliminate the need for protocol converters, reducing overall cabling costs by 30%–40%.
✅ Unrivaled Reliability: Adherence to industrial standards, coupled with advanced dual-layer shielding, guarantees stable communication in the harshest environments.
Enhanced After-Sales Assurance: All products carry a 2-year warranty with complimentary sample testing. Our technical team provides 24/7 support.
