Description
M12 D Coded 4 Pin Circular Connector characteristic

Description
- Pin count configuration: M12 D Coded 4 Pin Circular Connector are typically available in a 4-pin configuration, making them ideal for Ethernet and other high-speed data transfer protocol applications such as ProfiNet and EtherCAT. This configuration meets the needs of most industrial networks, ensuring fast and stable data exchange.
- High-performance materials: The M12 D Coded 4 Pin Circular Connector feature gold-plated contacts and corrosion-resistant housing materials. The high-quality material not only improves the electrical conductivity, enhances the durability of the connector, and can maintain stable operation under harsh working conditions.
- Protection level: up to IP67 or higher protection level, effectively prevent dust from entering, and can resist underwater immersion in a short time. The M12 D Coded 4 Pin Circular Connector also performs well outdoors or in wet, dusty environments.
- Application scenario: M12 D Coded 4 Pin Circular Connector are widely used in industrial Ethernet, Internet of Things (IoT), factory automation, sensor networks and other fields. Whether used to connect field devices or to build complex network architectures, M12D coded connectors provide the ideal solution.
