Category Insights

The M Series Electrical Connector is a type of circular connector used for power and signal transmission. It is known for its rugged design, making it suitable for harsh environments. These connectors have metal or plastic shells with threaded locking for secure connections. They come in various sizes, such as M8, M12, and M16. The "M" stands for metric, indicating their thread size. They are commonly used in industrial automation, robotics, and heavy machinery. Their waterproof and dustproof ratings (IP67/IP68) make them ideal for outdoor use. They support different pin configurations for power, data, and sensor connections.
M Series connectors are widely used in industrial and automotive applications. They connect sensors, actuators, and control systems in factories. In robotics, they provide reliable power and signal transmission. They are also used in renewable energy systems like solar panels and wind turbines. Their waterproof design makes them suitable for marine and outdoor equipment. Transportation systems, such as railways and electric vehicles, use them for secure connections. They are also found in medical devices and military equipment due to their durability. These connectors ensure stable performance in extreme temperatures and vibrations.
The "M" stands for metric, referring to the thread size (e.g., M8, M12, M16). These sizes indicate the diameter of the connector’s threaded locking mechanism. Metric sizing ensures compatibility with industrial standards.
Yes, many M Series connectors have IP67 or IP68 ratings. This means they are dustproof and can withstand water immersion. They are ideal for outdoor and wet environments.
Some M Series connectors support high-voltage applications. However, the voltage rating depends on the model and pin configuration. Always check the manufacturer’s specifications before use.
Industries like automation, automotive, aerospace, and renewable energy use them. They are also common in robotics, medical devices, and military equipment due to their durability.
Consider factors like size (M8, M12, etc.), pin count, voltage rating, and environmental protection (IP rating). Also, check if you need shielded connectors for noise resistance. Always match the connector to your application’s requirements.
