M8 Circular Connector
M8 Circular Connector
Engineered for industrial automation and sensor networks, the CONNODER M8 circular connector delivers robust signal integrity, environmental resilience, and plug-and-play compatibility in a compact 8 mm form factor.
- Standardized M8 Thread (M8×1): Ensures universal mechanical compatibility across global automation platforms and sensor ecosystems.
- Triple Termination Options: Choose from screw-clamp (field-wireable), solder (permanent cable assembly), or PCB mount (board-in) for maximum design flexibility.
- IP67/IP68 Protection: Fully sealed against dust, water immersion, and high-pressure washdown—ideal for food processing, outdoor robotics, and mobile machinery.
- A-, B-, and D-Coded Variants: Supports digital/analog sensors (A), fieldbus (B), and Industrial Ethernet (D)—enabling unified cabling for mixed-signal architectures.
- Gold-Plated Contacts (≥0.5 µm): Ensures low contact resistance, corrosion resistance, and stable performance over millions of mating cycles.
- Drop-in Compatibility: Fully interchangeable with M8 connectors from SICK, TURCK, Omron, Keyence, IFM, Balluff, Pepperl+Fuchs, Di-soric, and other leading brands—no system redesign required.
- IEC 61076-2-104 Certified: Manufactured to international standards for electrical performance, mechanical strength, and environmental endurance.
Designed for continuous operation in high-vibration and temperature-extreme environments, the CONNODER M8 connector maintains stable electrical contact and mechanical integrity—ensuring uninterrupted data and power transmission in mission-critical systems.
Typical Applications
Factory automation sensors & actuators, robotic end-effectors, distributed I/O modules, packaging machinery, agricultural equipment, and Industrial Ethernet nodes in PROFINET, EtherNet/IP, and Modbus TCP networks.
As a global manufacturer, CONNODER provides standard and custom M8 circular connectors—including pre-assembled cable solutions—Connoder is committed to driving the advancement of industrial automation through innovative, reliable and efficient circular connector solutions.
