Engineered for high-density signal and power integration in ultra-compact industrial systems, M9 circular connector delivers superior electrical performance and mechanical resilience where space is at a premium.

• High-Density Miniaturization: With a 9 mm thread diameter, it enables greater pin density than M8 while maintaining robust mechanical integrity—ideal for next-gen compact devices.
• Precision Threaded Coupling:  Metal-to-metal mating with full 360° coupling nut ensures vibration resistance and stable EMI shielding in dynamic applications.
• IP67 Protection:  Fully sealed against dust, high-pressure water jets, and aggressive cleaning agents—validated for washdown-intensive environments.
• Hybrid Signal & Power Options: Available in 2P, 3P,  4P, 5P, 6P and 8P configurations supporting mixed signal, data, and power transmission in a single interface.
• Full 360° EMI Shielding: All-metal housing and shielded contact carriers ensure signal integrity up to 500 MHz in high-noise industrial settings.
• Drop-in Compatibility:  Designed as functional equivalents to leading-brand high-density connectors—enabling seamless integration without system re-engineering.
• IEC-Aligned Reliability: Built to extended IEC 61076-2 design principles with >10 million mating cycles and -40°C to +85°C operational range.

The M9 connector combines miniaturization with industrial-grade durability. Its gold-plated contacts (≥0.75 µm), overmolded strain relief, and corrosion-resistant brass housing ensure stable performance in robotics, mobile machinery, and embedded sensing—even under continuous flexing or thermal cycling.

Typical Applications
Collaborative robot (cobot) joints, miniature vision & LiDAR sensors, AGV navigation modules, servo motor feedback systems, medical automation equipment, and compact IIoT edge devices.

At Connoder, we provide standard M9 connectors as well as custom-configured solutions—including pre-assembled cable sets with PUR or PVC jacketing—to meet your exact signal, power, and environmental requirements.
