As the backbone of the industrial connection field, circular connectors are widely used in various high-end technology equipment with their stable and reliable structural design, diversified interface forms and excellent environmental adaptability , and continue to evolve to meet future development needs.

Redefining the value of circular connectors

Traditionally, circular connectors are mostly used in industrial automation, rail transit, energy systems and other fields, emphasizing structural strength, protection level and electrical stability. In the current technology industry, especially in emerging fields such as intelligent manufacturing, medical electronics, robotics, autonomous driving, 5G communications and new energy equipment , the following new requirements are put forward for connection systems:

Smaller design to meet the installation requirements of miniaturized equipment;
Higher data transmission rate, supporting high-speed signal transmission;
Stronger electromagnetic shielding performance to ensure signal integrity;
More convenient assembly method to improve operation and maintenance efficiency;
A higher level of environmental sealing capability to adapt to extreme usage scenarios.

Through continuous iteration, circular connectors have gradually achieved the transformation from "connection" to "smart connection".
