Sometimes, when connecting two printed circuit boards (PCBs), known as mezzanine interconnects, you need a connector that can provide various levels of robustness, reliability, and performance. In such cases, you should look no further than the QMS-052-02-L-D-RA-PC4 from Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board).

The QMS-052-02-L-D-RA-PC4 is a two-row vertical card-edge connector. It features two 32-pin rows with an earth bar, which allows for a range of integrated circuit (IC) packages to be quickly and securely mounted and connected. This makes the connector suitable for use in surface-mounting technology (SMT) applications, such as cellphone and sensor technology.

The QMS-052-02-L-D-RA-PC4 is made from an FR-4 laminate. This provides good insulation, as well as making it flame-retardant. This, combined with its hermaphroditic design, which ensures that mating is correct first time, every time, makes the QMS-052-02-L-D-RA-PC4 perfect for use in a variety of apps, such as industrial automation and telecoms. It also has excellent mechanical strength, which makes it suitable for use in harsher environments.

The QMS-052-02-L-D-RA-PC4 encourages the clean and economical use of space on boards, thanks to its profile. This type of array has two ground slots, allowing for plain or ground braid. These are further complemented by hot-slug terminals, as well as the connector’s lances. These provide additional stability to the connector.

This connector is soldered directly to the board using reflow-soldering. The pins themselves are .020-in. square posts. These accommodate a wide range of wire coverings and insulation types. The QMS-052-02-L-D-RA-PC4 is rated for up to 750V (peak) and 16A (continuous), so it’s capable of carrying high-power applications. It’s also capable of up to 5000 cycles of use, making it an ideal choice for repeated connections (in industrial applications, for example).

The QMS-052-02-L-D-RA-PC4 is an excellent connector for a range of applications. It offers robustness, reliability, and performance in equal measure, which makes it a great choice for applications where space is limited and performance is non-negotiable.
