Built on Trust. Driven by the Full Marathon Spirit.
Founded in 2011 and headquartered in Shanghai, QM Connectors is a direct manufacturer of high-end interconnection solutions with dedicated medical, industrial, and defense-facing development capabilities.
In the early days, an infrared pioneer trusted QM enough to invest in tooling before success was guaranteed. The project succeeded, the customer became a global leader, and both sides grew together through long-term cooperation.
That same persistence continues in medical equipment, semiconductor tools, and special applications today: listen carefully, keep iterating, and do not stop until the solution is stable, manufacturable, and ready for real use.
Products are exported to Europe, the United States, Canada, Israel, Japan, South Korea, and India.
