The M9 connector achieves a breakthrough with its compact design of 9mm outer diameter. It strictly controls the shell tolerance within ±0.05mm. Even for the extremely narrow interface that customers complained couldn't fit from other brands, it can still be easily adapted. Combined with various designs such as straight type and front-panel pin type, no excessive space needs to be reserved at the rear of the panel, leaving sufficient flexibility for the equipment structure design.

The M9 connector directly raises the protection level to industry standards - the standard model reaches IP67, providing dust and water resistance and also being able to withstand temporary immersion in water. It can still function normally after being submerged in 8 meters of water for 24 hours. The housing is made of high-strength engineering plastics or metal materials, which can resist chemical erosion and mechanical impact.

The models with shielding function can effectively suppress electromagnetic interference. The 2-8 core spacing reduces crosstalk. The transmission of digital and analog signals is both precise and stable.
