QMS-078-06.75-L-D-PC4

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

The QMS-078-06.75-L-D-PC4 rectangular connector is an array edge type mezzanine connector, meaning it is a board-to-board connector that links two PCBs together. The “QMS” prefix stands for “Quad Mini Slotted” which means that this connector can house 4-row connections in either SIM, SIM or SMC type configuration. It has an outside width of .75 inches, and an outside length of 6.75 inches.

When it comes to rectangular connectors, there are a few key performance specifications that need to be considered. The connector should provide good electrical contact between the two systems. That means it needs to be able to provide a low contact resistance in order to reduce resistance losses while providing a secure connection that resists a large amount of electrical vibration. The contact housing should also be durable and reliable, providing a long-term connection.

The QMS-078-06.75-L-D-PC4 connector is designed with this in mind. It has gold plated solder tails that provide low contact resistances with 12-24 AWG wire. The copper alloy contact stafs provide a reliable connection, and the connector itself is made from strain relief for added durability and longevity. The contacts are also complimented with a robust and durable plastic housing for long-term reliability.

The overall design of the connector is also significant. This connector is a mezzanine design, which allows it to be normalized and stacked in different configurations. This allows engineers to build complex systems that are connected in series. The connector can also be used to route signals from one PCB to another, allowing for easier system changeovers.

The QMS-078-06.75-L-D-PC4 connector is a highly versatile and reliable board-to-board connector for applications requiring high performance and flexibility. Its mezzanine design allows for simple system expansion and changeovers, providing a long-term reliable connection. Its gold-plated contacts and copper alloy contact stays ensure a low contact resistance, and its strain relief housing is designed for long-term reliability.
