What Is an Automation Connector?

Automation connectors—also known as machine connectors—are specialized electrical interconnects designed for use in automated machinery, robotics, and industrial control systems. These connectors enable reliable transmission of power, signals, and data between sensors, controllers, actuators, and communication devices in factory automation networks.

Typically built with rugged materials and sealed against dust, moisture, and vibration, automation connectors ensure stable performance even in harsh industrial environments. Their quick-locking mechanisms (push-pull or threaded) make installation and maintenance fast and secure.

At MOCO, we offer a full range of automation connectors, including M8 and M12 circular connectors, industrial Ethernet connectors, and custom cable assemblies. All products are certified to international standards such as CE, RoHS, and ISO9001, and meet the demanding requirements of IP67/IP68 protection, EMC shielding, and high mating cycle life.

MOCO provides one-stop connection solutions, from design and prototyping to mass production—helping our clients achieve efficient, safe, and intelligent automation connectivity.

Types of Automation Connectors

Automation systems rely on multiple connector types depending on voltage, signal, and mechanical requirements. The main categories include:

M-Series Circular Connectors (M8, M12)

Compact, robust connectors ideal for sensors, actuators, and fieldbus communication. They are standard in industrial automation for data, power, and signal transmission.

Heavy-Duty Rectangular Connectors

Designed for high-current or multi-signal connections in manufacturing equipment, robotics, and machinery control panels.

Industrial Ethernet Connectors

Provide high-speed data transfer and reliable network communication for smart factories and IIoT (Industrial Internet of Things).

DIN Valve Connectors

Commonly used in pneumatic and hydraulic systems to connect solenoid valves and pressure sensors.

D-Sub Connectors

Offer secure signal and data connections in control units, instrumentation, and motion systems.

Fiber Optic Connectors

Ensure high-bandwidth, interference-free communication in high-speed automation networks and vision systems.

MOCO's M8 and M12 connectors, in particular, are engineered to meet the evolving needs of Industry 4.0 automation, supporting both signal and data transmission with superior shielding and long-term reliability.

Applications of Automation Connectors

Automation connectors are widely used across the entire industrial automation ecosystem, connecting equipment, sensors, controllers, and networks that drive modern manufacturing and robotics.

Key application areas include:

● Industrial Robots & Cobots – Enable flexible connections between robotic arms, servo motors, and control units, ensuring precise signal communication.

● Factory Equipment & Production Lines – Facilitate power and signal transfer in conveyors, assembly systems, and CNC machinery.

● Packaging & Processing Machines – Support high-speed operations and easy maintenance with durable quick-lock connectors.

● Automated Guided Vehicles (AGVs) and Logistics Systems – Offer reliable power and data transmission for mobility and navigation systems.

● Sensors & Actuators – M8 and M12 connectors provide compact, secure links between field devices and control modules.

● Smart Factory Networks – Industrial Ethernet connectors and fiber optics enable seamless communication for data-driven automation.

Automation encompasses a wide range of technologies and systems—from industrial processes and machinery to transportation, shipbuilding, aerospace, and energy management—all relying on high-performance connectors to minimize human intervention and maximize efficiency.
