 QMS-078-06.75-H-D-A-K is a type of rectangular connector belonging to the Arrays, Edge Type, Mezzanine (Board to Board) category.

 The body of this type of connector is an array of separate mount legs with an injection-molded cutting edge containing two 0.38mm stainless steel contact blades along its length. This provides a connection between two boards or mezzanines with up to 500 contact elements. This type of connector has a fast, easy, and reliable connection, allowing for a higher density on the board and increased routing flexibility.

 In terms of it\'s application field, this type of connector is ideal for applications requiring an optimal balance between signal integrity, power handling, and size. It is especially useful in telecom applications such as board-level component interconnect, and datacom applications such as I/O, hub, LAN,SCSI, and ISA. It is also applicable in embedded applications such as switching power supplies where power handling capabilities and ruggedness are needed.

 In regards to the working principles of the QMS-078-06.75-H-D-A-K, once the two boards are brought together, the two mating surfaces engage. The contacts then close like spring hinges from both sides. When closed, the contacts firmly grab each PCB trace. The two mating elements are otherwise separated by a spring force generated by black nylon plastic springs. At the same time, four external plated stainless steel clips serve to position the connector mating elements. At the same time, the screws on both sides are used to secure the plugs into the designed spaces and also to facilitate mounting.

 The QMS-078-06.75-H-D-A-K is a great way to ensure a reliable connection between two boards or mezzanines with up to 500 contact elements. It is ideal for telecom, datacom, and embedded applications where not only signal integrity but also power is a requirement for the system.
