The connector, as a medium for connecting signals or current transmission at both ends, can provide us with convenience under normal circumstances, but in an extremely harsh industrial environment, the condition of the connector cannot be guaranteed, and the transmission rate of the connector is stable. In this case, the industrial connector was born. This is a connector designed to resist harsh environments. It is designed to be used in extreme environments. It is tougher, safer and more capable than normal connectors. Guarantee performance. It has a variety of materials, sizes, contact layouts and types, and coupling designs. These circular connectors are commonly used for data, signal and power connections in the automation, manufacturing, military, aerospace, and transportation industries due to their rugged mechanical properties and easy connection. Due to the wide range of contacts, voltages and currents, they are also very versatile and flexible according to application requirements.
