Models and Specifications of Machine Vision Cables
Machine vision cables are critical components in ensuring high-speed, reliable data transmission for imaging systems in industrial, medical, and automation applications. Their design, materials, and performance specifications vary based on the demands of specific use cases. Below is a comprehensive overview of common models, key specifications, and factors to consider when selecting machine vision cables. Common Models of Machine Vision Cables Coaxial Cables Model Examples: RG-59, RG-179, RG-316 Applications: Ideal for transmitting high-frequency signals in cameras and sensors. Features: Single-core shielded design, excellent EMI resistance, and stable impedance (e.g., 75Ω or 50Ω). Hybrid Cables Model Examples: M12/M8 Hybrid Connector Cables Applications: Combines power, data, and signal lines in one cable for compact systems (e.g., robotic arms). Features: Multi-core shielding, high flexibility, and IP67-rated waterproof connectors. Fiber Optic Cables Model Examples: OM3/OM4 Multimode Fiber Applications: Long-distance, high-bandwidth transmission (e.g., large-scale factory networks). Features: Immune to EMI, low signal loss, and support for GigE Vision or Camera Link protocols. Flexible Robot Cables Model Examples: PUR/PVC Sheathed Continuous Flex Cables Applications: High-motion environments (e.g., robotic joints, automated guided vehicles). Features: Torsion-resistant, abrasion-proof jackets, and bend radii optimized for millions of cycles. Customizable Cables Model Examples: Vendor-specific designs (e.g., L-com’s Custom Machine Vision Cables) Applications: Tailored solutions for unique industrial setups. Features: Adjustable lengths, connector types (e.g., Hirose, Fischer), and shielding configurations. Key Specifications to Consider Conductor Material Copper: Standard for most cables, offering high conductivity and cost-effectiveness. Silver-Plated Copper: Enhances signal integrity in high-frequency applications. Shielding Foil Shielding: Lightweight protection against EMI. Braided Shielding: Heavy-duty EMI resistance (e.g., 85% coverage for industrial environments). Combined Shielding: Foil + braid for maximum interference protection. Impedance 75Ω: Standard for video signals (e.g., coaxial cables in GigE Vision systems). 50Ω: Common in RF and high-speed digital applications. Bending Radius and Flexibility Static Cables: Minimum bend radius ≥ 5x cable diameter. Dynamic Cables: ≤ 7.5x diameter for continuous motion (e.g., IGUS Chainflex® series). Jacket Material PVC: Economical and durable for general use. PUR (Polyurethane): Oil-resistant, flexible, and suitable for harsh environments. Teflon (FEP): High-temperature resistance (up to 200°C) for aerospace or semiconductor industries. Connector Types M12/M8: Common in industrial automation (IP67-rated). Hirose HR10A: Compact and reliable for high-density connections. BNC: Standard for analog video transmission. Bandwidth and Data Rate Coaxial Cables: Up to 6 GHz for 4K video. Fiber Optic Cables: 10 Gbps to 100 Gbps for high-speed networks. Certifications UL/CE/RoHS: Compliance with safety and environmental standards. ISO 9001: Quality assurance for industrial-grade cables. Matching Cables to Applications Factory Automation: Choose hybrid cables with M12 connectors and PUR jackets for EMI resistance and flexibility. Medical Imaging: Opt for fiber optic cables with sterilizable jackets and low-latency transmission. Outdoor Robotics: Select UV-resistant, waterproof cables with braided shielding. High-Temperature Environments: Use Teflon-jacketed cables with silver-plated conductors.
