What’s the Different Between M8 and M12 Connector?

In machine industrial automation and control, connectivity is of utmost importance. That's why Amsone Connectivity's M8/M12 Connector System has become a popular solution for reliable and safe communication in industrial settings. But what's the difference between M8 and M12 connectors? Let's take a closer look.

M8 Connectors: Small and Tough

The M8 connector is perfect for industrial sensors, thanks to its waterproof 3 4 6 8 pins screw with right angle and straight shape. It's pre-molded and can stay watertight even when submerged up to 1m within 30 minutes. These connectors are also tough, making them the best choice for really harsh environments.

One of the biggest advantages of the M8 connector is that it saves time when it comes to installing and maintaining wiring systems. You don't need an electrician or technician to do the job. Amsone Connectivity's M8 connector system offers a complete package, including connectors, IO modules, and cable assemblies. M8 connectors are widely used in applications ranging from printing processing to automation to intelligent robots.

M12 Connectors: More Complex and Versatile

While M8 connectors are mostly designed for sensors, M12 connectors have multiple types of code, such as A B D X T S L K M in Amissiontech. They're more complex, but also much more versatile. M12 connectors are circular with a 12-mm Fix screw locking system, making them ideal for factory automation applications such as sensors, actuators, industrial ethernet, and Fieldbus.

M12 connectors come in various sizes, ranging from 3 to 17 pins. The number of pins you choose will depend on your application requirements. For example, 3 and 4 pins are suitable for sensors and power, while 4 and 8 pins are ideal for PROFINET and ethernet. 4 and 5 pins are good for Fieldbus, CAN bus, and DeviceNet, while 12 pins are used for signal requirements.

In addition to the number of pins, you should also pay attention to the function of code. 

• A-Coded is used for signal transmission and data communication.

• D-Coded is used for power transmission and typically rated for higher current and voltage.

• X-Coded is used for communication and control applications.

• L-Coded is used for fiber optic communication and typically has a fiber optic terminal.

• Y-Coded is used for quick-release connections, allowing for fast and easy installation and removal.

M12 connectors come in both male and female genders, with straight and right angle types used in different areas depending on the application spaces. They're widely used in agriculture, alternative energy, communications, factory automation, measurement and control, robotics, and transportation.
