The M9 circular connector is composed of three key components: the shell, the insulator, and the contacts. The shell is often made of nickel - plated brass or stainless steel, providing both mechanical strength and corrosion resistance. The insulator is made from high - temperature - resistant engineering plastic, ensuring insulation performance and structural stability. The contacts feature a pin - and - socket design. Through precision stamping and electroplating techniques, they achieve low contact resistance and excellent electrical conductivity. Some products are equipped with snap - on or threaded locking mechanisms, which enhance connection firmness and effectively prevent disconnection in vibrating environments.
