The M9 circular connector consists of three core components: the shell, the insulator, and the contacts. The shell is mostly made of nickel - plated brass or stainless steel, which offers both mechanical strength and corrosion resistance. The insulator is crafted from high - temperature - resistant engineering plastic, ensuring insulation performance and structural stability. The contacts adopt a pin - and - socket design. Through precision stamping and electroplating processes, they achieve low contact resistance and excellent electrical conductivity. Some products are equipped with snap - type or threaded locking structures, which enhance connection firmness and effectively safeguard against disconnection in vibrating environments.
☑ This product is the female end of the M9 circular connector, with a vertical structure combined with encapsulated - molding wire. The vertical layout facilitates the vertical arrangement of wires. The encapsulation process integrates the connector and the wire, creating a neat structure and enabling easy installation, which is suitable for various device - integration scenarios.
☑ It can flexibly meet the requirements of 2 - 8 - core circuits. The combination of welding fixation and encapsulation protection ensures tight wire connections, reduces signal attenuation and transmission losses, and guarantees the stable transmission of power and signals.
☑ The encapsulated - molding wire has good bending - resistance and abrasion - resistance. It can withstand daily pulling and environmental erosion. Additionally, it provides insulation protection, enhancing the safety of use and extending the product's service life.
☑ It is widely used for wire connections in small - sized devices, instrumentation, etc. With features like flexible installation, convenient wiring, and stable transmission, it meets the needs of scenarios that require space adaptability and connection reliability.
