The M9 circular connector is composed of three core components: the housing, the insulator, and the contact piece. The housing is mostly made of nickel-plated brass or stainless steel, which combines mechanical strength and corrosion resistance. The insulator is made of high-temperature-resistant engineering plastics to ensure insulation performance and structural stability. The contact piece adopts a pin-hole design and achieves low contact resistance and excellent conductivity through precise stamping and electroplating processes. Some products are equipped with snap fasteners or threaded locking structures to enhance connection firmness and effectively prevent detachment risks in vibration environments.
☑ This product is the wire - end specification of the M9 connection cable male end, focusing on wire - to - wire connection scenarios. It adopts a simple and practical structural design. The male interface has strong adaptability, and the wire - end directly connects to the circuit, making the installation operation convenient and suitable for the wiring requirements of various devices.☑ It can flexibly meet the requirements of 2 - 8 - core circuits. The combination of welding fixation and encapsulation protection ensures tight wire contact, reduces signal attenuation and transmission losses, and guarantees the stable transmission of power and signals.☑ The wiring method is flexible and has a wide adaptability. Assembly can be completed without complex accessories. The welding connection has high firmness, which can withstand slight pulling during daily use. It is convenient for later maintenance, reducing the use cost.☑ It is widely used for wire connections in small - sized devices, instrumentation, etc. Combining the features of flexible installation, convenient wiring, and stable transmission, it meets the scenarios where space adaptability and connection reliability are required.
