  • Advantages : Our products are compatible with other M12 connector manufacturers such Binder , Murr , Turck , Phoenix , BELDEN . The M12 connectors could be customized by customer’s requirement , such as cable meterial , cable length , locking size , conductor size , wire definition , cable color .

Overmoulded M12 B Coded Cable

Overmoulded B coded M12 cables are a type of prewired M12 B coded connector that has been enhanced with a protective layer of molded material. The overmoulding process encases the connector and cable in a durable, protective material, providing additional protection against harsh environments, water, and dust. This type of cable is commonly used in applications that require a high level of durability and protection, such as industrial automation, transportation, and energy applications.


Field Wireable M12 B Coded Connector

The field wireable version of the M12 B-coded connector allows for on-site installation and repair, without the need for specialized tools or equipment. The connector is designed with screw or solder terminals that can make the cable installation easy and fast.

The B coded field wireable M12 connector shell can be made of either metal or plastic material, depending on the specific design and intended application. Metal shell connectors typically provide better electromagnetic shielding performance than plastic ones, due to the conductive properties of metal.

M12 B Coded Bulkhead Connector

The M12 B-coded bulkhead connector is a versatile and durable connector that can be used in a wide range of industrial applications. One of the key features of this connector is that it is available in a variety of mounting styles, including front mount and back mount. This flexibility makes it easy to integrate the connector into different types of equipment and systems.

Another important feature of the B-coded M12  bulkhead connector is that it can be used with a range of different connection types. The connector can be used with PCB mounting, allowing for easy integration with printed circuit boards. It can also be used with solder termination or prewired, which makes it easy to connect to other types of equipment or systems. The prewired option is especially useful in situations where the connector needs to be installed quickly or where the wiring is difficult to access.

The M12 B-coded bulkhead connector is also available in an SMD type, which is designed for surface-mount applications. This type of connector is ideal for use in applications where space is limited or where the connector needs to be mounted directly onto a circuit board. Additionally, the square type is another variation of the M12 B-coded bulkhead connector that is suitable for use in applications where a more compact and space-saving design is required.

M12 B Coded Splitter

M12 B-coded splitters are devices that are used to split and distribute data signals in industrial automation systems. These splitters are designed to work with M12 B-coded connectors, which are commonly used in fieldbus applications.

M12 B-coded splitters play an important role in fieldbus applications, as they enable the connection of multiple devices to a single fieldbus network. These splitters are designed to split the incoming data signal into multiple output signals, which can then be distributed to different devices in the system. This allows for greater flexibility in system design and makes it easier to add or remove devices from the network.

B-coded M12 splitters are available in different configurations, such as T-splitters, Y-splitters, I-splitters, they enable the connection of one input signal to two output signals, with customized M12 B-coded splitters can enable the connection of one input signal to three or more output signals.

Why M12 B Coded Connector Is Used For Profibus

B-coded M12 connector is a reliable, standardized, and easy-to-use connector that meets the requirements for high-speed data transmission in industrial automation and control systems, making it a popular choice for Profibus networks.

#1 Robustness: 

The B-coded M12 connector is designed to withstand harsh industrial environments, such as exposure to moisture, dust, and vibration. It has a rugged metal housing that provides a secure and reliable connection in challenging conditions.

#2 Standardization: 

The B-coded M12 connector is part of the IEC 61076-2-101 standard, which defines the electrical and mechanical properties of connectors for industrial automation and control systems. Profibus, being an industrial communication protocol, conforms to this standard and therefore uses the B-coded M12 connector for its connections.

#3 High-speed communication

Profibus requires a high-speed data transmission rate, which is achieved by using a shielded twisted pair cable and a connector that can handle high-frequency signals. The B-coded M12 connector has four or five contacts, which are sufficient for transmitting high-speed data and power signals in a compact form factor.
