With the explosive growth of the number of elevators in China, the safety of elevators has become the focus of the public's livelihood. As the control system of elevator operation brain, there are a lot of interfaces on the edge of the main control board to connect important control equipment, including speed feedback device, frequency converter, door lock and safety circuit, hoistway signal and function input, etc. These interfaces realize the signal transmission between devices through connectors. Adhering to 20 years of technology research and development, Shinning connector has accumulated rich experience in the elevator industry. The products have high vibration resistance and impact resistance, which can ensure the safe connection between equipment.
