Product Introduction
D Sub Mixed Contact Connectors are specialized interface components
that combine signal, power, or coaxial contacts in a single compact
connector body. These connectors are widely used in industrial
control systems, robotic equipment, and communication interfaces
where both low-voltage data and high-current power must be
transmitted through one port.
