M12 D-coded connector typically feature 4-pin , it’s designed to provide reliable and fast data transmission of up to 100 Mbps, making it ideal for industrial applications that require high-speed communication, it has default conductor 22AWG, can be made with CAT5e PVC, PUR, drag chain ethernet cables.

  • Types : M12 D-coded ethernet connectors are available in various forms to suit different requirements, such as D-coded M12 cables, D-coded M12 field attachable connector, SMD and PCB mount M12 D-code connector, M12 D-code bulkhead connector, M12 to RJ45 adapters, M12 to RJ45 ethernet cables.
  • Application : The D-coded M12 connectors are often used in industrial Ethernet applications, as well as in machine vision systems, factory automation systems, process control systems, and robotic systems. With its high data transfer speeds and rugged construction, it is a popular choice for many industrial and factory automation applications that require fast and reliable data transfer.

Prewired M12 D Coded Cables

M12 D-coded Ethernet cable is used for data transmission, normally is shielded, one end is D-coded M12 cable which can be male or female, the other end is open or with RJ45 connector(also can be D-code M12 connector), the cable jacket have PVC, PUR for option, if used for robots or machine vision, sometimes will use drag-chain cable(PVC or PUR jacket).

  • PVC : PVC (Polyvinyl Chloride) is a commonly used material for cable insulation and is known for its durability and low cost. PVC cables are flexible and easy to handle, making them a popular choice in many industries. They are also resistant to moisture, heat, and chemicals, which makes them suitable for a wide range of applications. However, PVC is not suitable for use in environments with high mechanical stress, high temperatures, or exposure to oils, fuels, and solvents.
  • PUR :  PUR (Polyurethane) is a more advanced insulation material that is designed for harsher environments. PUR cables are highly flexible and have excellent resistance to abrasion, cutting, and tearing, making them ideal for use in dynamic applications such as robotics and automation. They are also resistant to oil, fuels, and solvents, and can operate in a wide range of temperatures, from -40°C to 80°C. However, PUR cables are typically more expensive than PVC cables.
  • Drag-chain cable : Drag-chain high flex Ethernet cable is a type of Ethernet cable that is specifically designed to be used in dynamic applications where the cable needs to withstand repeated bending and flexing, such as in robotic or automation systems. This type of cable is typically installed inside a drag chain, which is a type of protective housing that helps to guide and protect the cable as it moves. The design of drag-chain high flex Ethernet cable includes a highly flexible jacket material that is capable of withstanding repeated bending without cracking or breaking. The cable often has special shielding and insulation to reduce electromagnetic interference (EMI) and ensure reliable data transmission.

M12 D Coded Field Wireable Connector

D code M12 field wireable connector have solder and screw termination, made of PA66 or Zinc alloy shell.

  • Solder termination is generally more permanent than screw termination and can provide a stronger electrical connection. However, it is not as convenient to install as screw termination and may not be suitable for certain environments or applications where vibration or extreme temperatures are a concern. 
  • Screw termination, on the other hand, is easier to install and allows for more flexibility in terms of making and breaking connections. However, it may not be as reliable as solder termination in situations where vibration or extreme temperatures are present.

M12 D Coded Bulkhead Connector

D-coded M12 bulkhead connector is used for a wire-to-board applications, it’s mounted from the front or back of the bulkhead, and are available in solder type(prewired available), SMD (surface mount device) ,through-hole PCB mount styles(with straight or right angled mounting options). The PCB mount D code M12 connectors had been used a lot for industrial ethernet switches.

  • Solder bulkhead connector : prewired with default wire definition or accord to customer’s requirement, without wires is available, front mount or back mount
  • PCB M12 D-coded connector : Mostly are back panel mount, also called THD(through hole device), solder to PCB with wave soldering machine, it has straight and 90 degree right angled shape.
  • SMD M12 D-coded connector : SMD is short of surface mount device, the connector will be preciously placed to the PCB with SMT machine, the reflow soldering machine will melt the solder paste , after the solder paste cools, the connector installation is finished.

D Coded M12 Splitter

D code M12 splitters are available in a range of styles, including panel mount, Y-type, and T-type. Y-type and T-type could be purchased with connectors already attached or as open ended cables. They are used in a wide range of applications, including industrial automation, factory automation, and machine control.

M12 D Coded Ethernet Cable

M12 D-coded 4-pin to RJ45 cables are also called D code M12 ethernet cables, they are used to connect devices with M12 connectors to devices with RJ45 connectors. RJ45 connectors, on the other hand, are a type of Ethernet connector commonly used in networking applications. They have a rectangular housing with eight pins arranged in a standard configuration. M12 D-coded 4-pin to RJ45 cables are used to connect devices such as industrial ethernet switches and other industrial control systems to devices such as computers and routers. They are typically made of high-quality materials to ensure a reliable and stable connection.
