The part number **21349500405015** corresponds to a high-performance **M12 Circular Connector** from the **HARTING** M12 Slim Design series. These components are critical in industrial automation for transmitting data at high speeds in space-constrained environments. --- ## 🛠️ Technical Specifications This specific part belongs to the **HARTING har-speed** family, designed for Ethernet connectivity in industrial settings. | Feature | Specification | | :--- | :--- | | **Connector Type** | M12 Circular Connector | | **Gender** | Male | | **Coding** | X-Coded (High Speed) | | **Number of Contacts** | 8-Pin | | **Data Transmission** | Up to 10 Gbit/s (Cat. 6A) | | **Termination Method** | Crimp Terminal | | **Shell Material** | Zinc Die-cast (Nickel Plated) | | **IP Rating** | IP65 / IP67 (when mated) | --- ## 🔍 Key Characteristics ### 1. X-Coding for High Speed Unlike standard A-coded connectors used for sensors/power, **X-coding** is specifically designed for high-bandwidth data. The internal shielding isolates the four pairs of wires, minimizing crosstalk and allowing for **10 Gigabit Ethernet** performance. ### 2. Slim Design The "Slim Design" refers to the reduced external diameter of the connector. This allows for high-density integration on devices where port space is limited, such as: * Compact Industrial Switches * IP cameras * Compact PLC modules ### 3. Crimp Termination This part uses crimp contacts rather than screw or solder terminals. Crimp connections are preferred in high-vibration environments (like railway or robotics) because they provide a gas-tight, mechanically stable connection that does not fatigue like solder. --- ## 🏗️ Typical Applications * **Industrial Automation:** Connecting sensors and actuators to high-speed fieldbus systems. * **Transportation:** Used in railway applications for passenger information systems and Wi-Fi networks (often compliant with EN 45545 fire protection standards). * **Surveillance:** Powering and receiving data from high-definition IP cameras via PoE (Power over Ethernet). ---
