### Electronic Specifications: M2REB-SB2-R/UL The **M2REB-SB2-R/UL** is a high-performance, shielded multi-core cable typically used in industrial automation, robotics, and signal transmission applications. It is designed to meet strict international safety standards (UL/CSA) and provide electromagnetic interference (EMI) protection. --- ### 1. Key Technical Specifications The following table outlines the core electronic and physical attributes of the cable: | Parameter | Specification | | :--- | :--- | | **Core Count** | 2 Cores (SB indicates Twisted Pair/Shielded) | | **Conductor Material** | High-purity Stranded Copper | | **Shielding Type** | Braided Shield (SB - Shielded Braid) | | **Voltage Rating** | 300V (Standard for UL/CSA signal cables) | | **Temperature Range** | -20°C to +80°C (Fixed installation) | | **Flame Retardancy** | UL VW-1 / CSA FT1 | | **Jacket Material** | Oil-resistant PVC | --- ### 2. Breakdown of the Model Name Understanding the nomenclature helps identify the electronic capabilities: * **M2REB**: Represents the series, often signifying a highly flexible (robot-grade) cable suitable for repetitive bending. * **SB**: Stands for **Shielded Braid**. This is critical for electronic environments with high noise, as it prevents EMI from disrupting the signal. * **2**: Indicates the number of internal conductors/cores. * **R**: Generally refers to "Robot" or "Reel" grade, implying high torsion and bending resistance. * **UL**: Signifies compliance with Underwriters Laboratories standards, ensuring safety for the North American market. --- ### 3. Electronic Features and Applications #### Noise Suppression The integrated braided shield acts as a Faraday cage. This is essential for: * Connecting sensors to PLCs. * Transmitting low-voltage data signals in factories with heavy motors. #### Flexibility & Durability Unlike standard electrical wire, the "R" (Robot) designation means the internal copper strands are much finer. This reduces the risk of **metal fatigue** during constant movement, ensuring the electrical continuity remains intact over millions of cycles. #### Chemical Resistance The outer sheath is treated to be resistant to oils and coolants, preventing the insulation from breaking down and causing short circuits in CNC or machining environments. ---
