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:

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.

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.

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.

Benefits of Automation Connectors and How to Choose the Right One

Benefits:

Reliability & Safety: Resistant to vibration, dust, and fluid ingress (up to IP68).

Ease of Installation: Push-pull, screw, or bayonet locking ensures fast and secure mating.

Signal Integrity: 360° EMC shielding prevents interference in complex environments.

Durability: High mating cycles (≥5000) guarantee long service life.

Versatility: Suitable for data, signal, and power transmission across multiple automation systems.

How to Choose:

Define Application Needs: Determine voltage, current, and signal types.

Consider Environmental Conditions: Choose IP-rated connectors for dust/water exposure or vibration-heavy environments.

Match Connector Type: M8 for compact sensors, M12 for robust field connections, rectangular for multi-pin solutions.

Check Standards & Compatibility: Ensure compliance with IEC, UL, or fieldbus standards.

Plan for Maintenance: Opt for connectors with quick-lock mechanisms and easy field replacement.

With MOCO’s expert engineering support, you can select the optimal connector type for your automation project—achieving long-term reliability and high system efficiency.
