As technology continues to advance, the need for reliable and efficient connectors becomes increasingly important in various industries. One such connector that has gained popularity in recent years is the M12 connectors.

The term “M12 molded connector” typically refers to a type of electrical connector that follows the M12 standard. The M12 connector is a circular connector commonly used in industrial automation and control systems. It features a threaded coupling mechanism that provides a secure and reliable connection.

The “molded” aspect of the connector refers to the manufacturing process used to create it. In this case, the connector is formed by molding the connector body around the cable, providing a more robust and integrated construction. This molding process helps protect the internal components and wiring from environmental factors such as moisture, dust, and mechanical stress.

M12 connectors are available in various configurations, including male and female versions, with different numbers of pins or contacts. They can be found in different styles, such as straight connectors, right-angle connectors, or bulkhead connectors, to suit different installation requirements.

These connectors are commonly used in industrial applications, such as factory automation, process control, robotics, and sensor connections. They provide a reliable and compact solution for connecting sensors, actuators, and other devices in harsh environments.

It’s important to note that the M12 standard encompasses different types of connectors, including those used for Ethernet (M12 D-coded), sensors/actuators (M12 A-coded), and power applications (M12 L-coded). The specific type of M12 molded connector would depend on the intended application and the coding used.


  • Sensors: In sensor applications, the M12 connector is often used to provide power and signal connections to the sensor.
  • Actuators: The M12 connector is often used to connect actuators such as solenoid valves, pneumatic cylinders, and motors in industrial automation applications.
  • Control systems: The M12 connector is often used to connect various components of a control system, including programmable logic controllers (PLCs), human-machine interfaces (HMIs), and other devices.
  • Fieldbus systems: The M12 connector is commonly used in fieldbus systems, which are used to connect sensors, actuators, and other devices in industrial automation applications. The connector’s compact size and reliable performance make it an ideal choice for use in Fieldbus systems such as Profibus, Devicenet, and CANopen.
