Industrial Connection Technology – Reliable Signal, Data & Power Transmission

In today's automation and industrial environments, connection technology is essential for system reliability and performance. Circular connectors are the backbone of this technology—providing robust, compact, and efficient solutions for transmitting power, signals, and data. As pre-assembled and 100% factory-tested components, they help minimize installation time and reduce wiring errors, making them ideal for fast-paced industrial operations.

Core Benefits of Circular Connectors

Unlike traditional plug systems that may loosen or disconnect under mechanical stress, circular connectors feature a secure threaded coupling. This ensures a stable, vibration-resistant connection, even in demanding industrial applications. With a wide range of connector sizes, pole configurations, and mounting options, Murrelektronik’s connectors offer compact solutions without compromising electrical performance.

Reliable Signal Transmission in Automation

When used for signal applications, circular connectors provide consistent and interference-free communication between devices and control units. Whether it's connecting warning lights, valves, or proximity sensors to PLCs, they ensure dependable signal flow. They also support bidirectional signal exchange, enabling accurate communication of temperature, speed, or magnetic field changes from sensors to control systems—even in harsh environments.

Designed for Data Communication

Circular connectors are increasingly used for high-speed data transmission in industrial settings. Their robust build makes them suitable for environments with:

• Vibration, dust, and moisture: Ensuring long-lasting and secure connections
• Quick-connect capability: Supporting tool-free installation and fast maintenance
• High bandwidth: Enabling real-time control, monitoring, and data acquisition
• Protocol versatility: Supporting Industrial Ethernet, PROFINET, EtherCAT, Profibus, CANopen, and DeviceNet
• Safety locking mechanisms: Preventing unintentional disconnection and enhancing system uptime

M12 connectors are a standard solution for transmitting digital data in harsh industrial environments, ensuring consistent Ethernet-based communication across machine networks.

Power Distribution Made Easy

For peripheral device power—such as lighting, sensors, or industrial cameras—circular connectors deliver reliable electrical supply through durable, threaded designs. These connectors stay firmly in place even under movement or strain, but can still be manually disconnected when needed. They are an excellent choice for systems requiring both resilience and flexibility in power connections.

Form Factors & Connector Types

Circular connectors are available in various shapes, sizes, and configurations. In addition to straight connectors, angled designs help optimize cable routing in space-constrained installations. Choosing the correct number of poles and conductor sizes ensures optimal performance, preventing signal loss and mechanical stress.
