RailMac Control Connector (Power-Concentrated EMU)
Designed to meet GB/T 25022.3-2023 (Rail Transit Rolling Stock Electrical Connectors – Part 3: Communication Control Connectors), this Control Connector is a specialized solution for rail transit systems, integrating network and control signal transmission in a single, robust unit. Its integrated network module, paired with continuous shielding functionality (maintained unbroken during use), ensures stable, interference-free signal transfer—critical for consistent communication in dynamic rail environments.
A standout feature is its multi-layered guiding structure: the socket’s left-right draw hooks include a limiting function to restrict plug wobble, enabling smooth, reliable “blind mating” (insertion without visual alignment). This design not only simplifies operation but also protects pins from damage, enhancing long-term durability. For frequent plugging scenarios (common in rail maintenance and operation), the connector uses axial positioning via front and rear insulation plates—delivering precise insertion guidance and strong positioning force to withstand repeated use.
Composed of a plug and socket, the connector is equipped with 54 contact pairs and 3 ports, balancing high connection capacity with compact form. Whether for on-board communication systems or control signal distribution, it combines compliance with industry standards, advanced shielding, user-friendly blind mating, and rugged positioning to support the reliable, continuous operation of modern rail transit electrical networks.
Advantages of RailMac Control Connector (Power-Concentrated EMU)
This connector integrates network and control signals, with the network module installed within the connector. After mating, it provides continuous shielding without interruption during use.
It employs a multi-guided structure, and the left and right hooks of the socket have a movement-limiting function, restricting plug movement and ensuring smooth and reliable plug insertion into the socket. This effectively protects the pins and enables “blind mating.”
The contact pairs utilize axial positioning with front and rear insulating plates, providing excellent insertion guidance and high positioning force, suitable for frequent mating and unmating.
According to GB/T 25022.3-2023 “Railway Transportation – Electrical Connectors for Locomotives and Rolling Stock – Part 3: Communication Control Connectors,” this connector consists of a plug and a socket, with 54 contact pairs and 3 ports.
