4Pin/5Pin M12 Circular Industrial Connector with Lock Catch

Industrial M12 Circular Connector with Lock Catch – Reliable 4Pin/5Pin Solution for Harsh Environments

This robust and precision-engineered M12 circular connector offers a secure, vibration-resistant connection ideal for demanding industrial applications. Designed with a durable locking mechanism and a standardized 12mm thread joint, it ensures stable performance even in high-shock environments such as factory automation systems, robotics, and mobile machinery. Whether you're integrating sensors, data transmission modules, or control units, this connector delivers consistent electrical integrity and signal reliability.

Key Features & Benefits:

• Secure Threaded Locking Mechanism – Prevents accidental disconnection due to mechanical stress or environmental factors like vibration and shock.
• Quick RF Coupling Design – Enables fast, tool-free mating and unmating, improving maintenance efficiency and reducing downtime.
• Wide Compatibility – Supports both DC power delivery and high-speed data signal transmission across 4-pin and 5-pin configurations.
• Durable Construction – Made from premium materials including brass contacts and UV-resistant plastic housing for long-term reliability in extreme conditions.
• Global Industrial Standards Compliance – Meets IP67 protection rating and conforms to IEC 61076-2-101 specifications for industrial-grade connectors.

Engineered for maximum durability and ease of integration, this M12 circular connector is more than just an interface—it’s a critical component in modern smart manufacturing, intelligent transportation systems, and automated production lines. Its compact form factor allows seamless installation in tight spaces while maintaining full electromagnetic compatibility (EMC) and minimal signal loss over extended cable runs. The lock catch feature provides tactile feedback during coupling, ensuring proper engagement without over-tightening—a key advantage in repetitive assembly tasks.

Ideal Applications:

From small-scale sensor networks in logistics automation to high-reliability connections in electric vehicle charging stations, this connector excels in diverse sectors. It's commonly found in packaging equipment, medical imaging devices, drone power systems, and instrumentation panels where stable connectivity under dynamic loads is essential. In addition, it supports industrial Ethernet protocols like PROFINET, EtherCAT, and DeviceNet—making it a versatile choice for IIoT deployments and Industry 4.0 infrastructure.

Customer Feedback Highlights:

Users consistently praise its reliability in harsh settings—from dusty factory floors to outdoor construction sites. One engineer noted that the quick-connect design saved nearly 30% in service time during routine inspections. Another user highlighted how the anti-vibration feature eliminated intermittent signal drops in a conveyor belt monitoring system, significantly boosting process stability.
