M12is a kind of circular connector equipped with 12mm locking thread structure, generally with IP protection level, can prevent the intrusion of liquid and solid. Born in 1985, the M12 connector can be said to be all kinds of universal interface in the "old generation".
M12 Connectors
Prior to the development of the M12 interface, engineers had to pull wires directly under complex environmental factors and harsh industrial production conditions, or repeatedly replace connector assemblies that were damaged due to their inability to withstand the environment. The M12 connector was initially released in 3-pin and 4-pin versions. At that time, the M12 was not as good as its predecessor, the RK30, in terms of the maximum current permitted, but it could achieve IP67 protection, so it was quickly popularised and widely used in the industrial sector. Today, this tried-and-tested, durable connector has not only been developed in 5-pin, 8-pin, and 12-pin configurations, but also in a variety of new locking methods, such as bayonet, push-pull, and other types of locking, in order to better meet the needs of the development of industrial applications.
M12 Connectors
The M12 is small in size, large in volume and rich in configuration and coding. Due to the specificity of industrial applications,the M12interface not only provides a variety of pin numbers, but also uses a variety of key codes to prevent misplugging. These pins and codes will correspond to different uses according to different properties. They are generally used for sensors, DC and Ethernet. The most widely used M12 code types are A code, B code, D code, and X code. Of all the codes, A-code, B-code and X-code were first developed and are still in use today. In today's high-speed industrial Ethernet, there is a growing need for X-code connectors, which will eventually replace A-code and D-code in Ethernet applications.
M12 is already in use everywhere. The development of the M12 can best be summarised by the word "innovation". Since its introduction, M12 has guaranteed reliable connections and stable transmission in the harshest environments and is the interconnection system of choice for industrial automation, mainly for sensors, actuators, industrial Ethernet and fieldbus devices. It can be said that M12 connectors are continuously helping to usher in one revolution after another in the field of industrial automation.
M12 Connectors
In addition to factory automation, due to their corrosion resistance, M12 connectors and M12 cable assemblies are being put to use in more and newer fields, such as measurement and control, communication, transport, robotics, agriculture, new energy applications, etc.
