Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board)

QMS-052-02-SL-D-RA-K rectangular connectors are a type of array connectors used for mezzanine board-to-board applications.

These type connectors have two rows of pins arranged in a rectangular pattern to form an array. The array structure helps them to be used as edge-type connectors, where one row of the array connector is connected to the PCB, and the other row of contacts, the array connector’s edge contacts, is used to make contact with the mezzanine board.

The QMS-052-02-SL-D-RA-K connectors come in a wide variety of configurations. There are 2, 4, 5 and 8 row configurations, with different pin configurations from 8 to 396 pins. The contact pitches can also vary from 4.31 mm to 11.5 mm.

These connectors are popular in a wide range of applications, ranging from telecommunications to consumer electronics. They are commonly used on mezzanine boards which need to make contact with a PCB.

Working Principle

The QMS-052-02-SL-D-RA-K connectors employ a dual-row design for making contact with the PCB and the mezzanine board. The row of contacts along the side of the connector is used to make contact with the mezzanine board, and the other row of contacts is used to make contact with the PCB. This type of connector is designed to allow electrical connections between the two boards of a mezzanine board, without having to make multiple connections.

The contacts of the QMS-052-02-SL-D-RA-K connector are made out of a special gold-plated material, which ensures that the contact between the two boards is both secure and reliable. The contacts are also designed to provide a tight fit, which prevents the connections from loosening over time.

The QMS-052-02-SL-D-RA-K connectors feature shields that provide EMI protection to the connections between the two boards, which helps to reduce the chances of interference from outside sources. The shielding also helps to reduce crosstalk and other types of electrical interference between the two boards.

In order to ensure that the electrical connections remain secure and reliable, the QMS-052-02-SL-D-RA-K connectors feature a locking mechanism, which locks the contact points into place. This helps to ensure that the electrical connection between the two boards is secure and reliable.

Conclusion

QMS-052-02-SL-D-RA-K rectangular connectors are a type of array connectors used for mezzanine board-to-board applications. They come in a variety of configurations and are used in a wide range of applications. They feature gold-plated contacts for a secure and reliable connection, as well as shields for EMI protection. Their locking mechanism ensures that the connections remain secure and reliable.
