Introduction of QMS-078-01-L-D-RA-PC8

QMS-078-01-L-D-RA-PC8 is a type of rectangular connector in the edge type family of connectors. It belongs to the group of arrays, edge type, and mezzanine (board to board) connectors. Its purpose is to connect various electrical components, allowing them to talk and work together. It is most commonly used in critical applications such as aerospace, automotive, industrial machinery, medical, and consumer products.

Application field

QMS-078-01-L-D-RA-PC8 connectors are designed for providing reliable power, data, and control connections. It makes the most sense when used to connect multiple integrated circuits, printed circuit boards, and device mounted connectors. It is typically used for high-speed and low- power electric systems. This type of connector is also commonly used in applications such as automotive, medical, consumer products, industrial machinery, and aerospace. Examples of these applications include engine control systems, mission-critical auto-pilots and navigation systems, body control systems, electronic medical instruments, medical devices, electronic test benches, splitters, communication equipment, and enterprise networks.

Working Principle

The basic working principle of QMS-078-01-L-D-RA-PC8 connectors is designed to allow electrons to pass from one component to another. It utilizes a connection between different pins on two separate components to enable data and power to flow between them. The components are attached using two halves of a bracket, and two screws, and the electrical connection is made through a series of spring-loaded pins inside the connector. As the pins move inwards, they make contact with their counterparts on the other component and the connection is established. The pins offer a high-level of accuracy in terms of the electrical connection and, when combined with a proprietary locking mechanism, offer a secure connection capable of withstanding extreme temperatures, vibrations, and shock.

Conclusion

QMS-078-01-L-D-RA-PC8 connectors belong to the group of arrays, edge type, and mezzanine (board to board) connectors. It is used to connect various electrical components together and is most commonly used for applications in automotive, medical, consumer products, industrial machinery, and aerospace. The basic working principle of these connectors involves connecting the two halves of a bracket, and using spring-loaded pins to make contact with the corresponding pins on the other component. This type of connector provides a reliable and secure connection and is capable of withstanding extreme temperatures, vibrations, and shock.
