The M12 circular connector, as a standardized threaded locking circular electrical connector, is characterized by its 12-millimeter threaded housing design, ensuring compatibility and interchangeability among products from multiple manufacturers. It is typically used for connections between sensors, actuators, and control devices, and can operate stably in harsh environments such as dust and moisture, thereby enhancing the reliability of system operation. For engineers choosing connectors, understanding its structural dimensions and industry standards is the foundation for achieving long-term stable operation.
☑Standardized design: The M12 connectors comply with international standard IEC 61076-2-101, ensuring interchangeability and compatibility between different manufacturers.
☑Protection level: IP67 or higher protection level can effectively prevent dust, water and other pollutants from entering in harsh environments.
☑Vibration resistance: Thread locking mechanism is used to ensure stable electrical connections can be maintained under vibration and impact conditions.
☑Coding diversity: Provides various encoding types such as A, B, C, D to avoid misinterpolation and adapt to different application need
☑Transmission capability: Supports signal transmission over Ethernet connections up to 1 Gbps, while also suitable for DC power connections, making it an ideal choice for general-purpose sensors, actuators and IO-Link devices.
☑Voltage and Current Rating: Depending on the application scenario, the A-encoded connector can support voltage ranges from 30V to 250V, and current capacity from 1.5A to 4A.
☑Durability: The high-quality brass or phosphorus copper terminals have been solid gold-plated, with strong oxidation resistance, ensuring a plug-in and unplugging life of more than 500 times.
