Working Principle

QMS-078-02-SL-D-A is designed to work as an edge type mezzanine. This means that it is mounted onto a board or PCA such that electrical contacts are made between the board and the connector. The signal and power pins of the connector are exposed to the mating board, providing a reliable connection. These pins are designed to have a low contact-resistance, which ensures that signals and power are transferred efficiently and without interference. The connector is also designed to be self-locking, which means that it is secured in place by a latch mechanism that is activated when the mating board is connected. This ensures that the connector stays firmly in place even when exposed to vibration and shock. The connector is rated for a maximum voltage of 500V and a maximum current of 10A. This is suitable for a number of applications, and provides sufficient current for a number of electronic devices.

Conclusion

QMS-078-02-SL-D-A is a rectangular connector that is designed to provide a reliable electrical connection between boards and PCAs. The connector is suitable for a number of applications, including computer systems, factory automation equipment, motor control systems, and medical devices. The connector offers a relatively small form-factor, while still providing a high current rating of 10A and a relatively low contact resistance. The connector is also designed to be self-locking, providing a secure and reliable connection when mated to a board or PCA.
