Purpose of M12 Circular Connector Codes

　      M12 circular connectors are integral components in industrial automation, providing robust and reliable connections for sensors, actuators, and communication interfaces. A critical aspect of these connectors is their coding system, which ensures proper mating and prevents misconnections.

Understanding M12 Connector Coding

The M12 connector coding system utilizes letter designations to define specific applications and electrical characteristics, preventing incorrect connections and ensuring compatibility across various industrial systems. Here are the primary M12 connector codes:

· A-Code: Commonly used for sensors, actuators, and standard I/O applications, these connectors typically have 3 to 17 pins and support DC power and low-frequency data transmission.

· B-Code: Designed for fieldbus connections such as Profibus, B-coded connectors usually feature 4 or 5 pins and are employed in non-Ethernet fieldbus systems.  

· C-Code: Utilized for AC power applications, C-coded connectors typically have 3 to 6 pins and are suitable for connecting AC-powered sensors and actuators.  

· D-Code: These 4-pin connectors support data transmission up to 100 Mbps and are commonly used in industrial Ethernet applications, including PROFINET and EtherNet/IP.  

· X-Code: Engineered for high-speed data transmission up to 10 Gbps, X-coded connectors typically have 8 pins and are suitable for advanced industrial Ethernet applications requiring high data throughput.

· S-Code: Intended for AC power systems, S-coded connectors feature 2+PE or 3+PE pin configurations and are rated for 12 A at 300 Vac, commonly used in motor and control applications.

· 

· T-Code: Designed for DC power applications, T-coded connectors have 2 to 4 pins and can carry up to 12 A at 60 Vdc, making them suitable for DC motor connections and LED lighting systems.

· L-Code: Utilized for DC power distribution, particularly in fieldbus systems like PROFIBUS, L-coded connectors can carry up to 16 A at 63 Vdc and typically have 4 or 5 pins.

· K-Code: These connectors are used for AC power applications, especially in three-phase systems, capable of handling higher currents and voltages suitable for industrial machinery.

· M-Code: M-coded connectors are designed for three-phase AC power connections, supporting applications that require compact connectors with high power transmission capabilities.

· Y-Code: Hybrid connectors that support both power and data connections in a single unit, Y-coded connectors are used in applications requiring simultaneous transmission of power and data.
