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

Rectangular mezzanine connectors are available on the market in various sizes, configurations, and levels of electrical insulation. These connectors are typically used in the development of complex, high-density board-to-board interconnects.

The QMS-052-05.75-L-D-A-K mezzanine connector is one such example. This component is considered to be a “multi-row”, “edge-type” connector, as its length is roughly twice the width of the contact area. This connectivity feature makes it especially well-suited for complex systems development, and is often used in the formation of mezzanine and mated connectors.

The QMS-052-05.75-L-D-A-K is created through the use of high-quality contact retention processes, and conforms to ISO 9001:2015 standards. The contact surface includes a 2.75mm width blade and a lowered contact pitch. It measures 52mm wide by 7.5mm long (2.2" x 0.3") and supports signal running up to 3amp at 500Vdc. The contact area includes two tin-plated phosphor bronze contacts and a blind-mated 25µin gold plated contact.

Because of its size and design, the QMS-052-05.75-L-D-A-K connector is ideal for applications such as medical imaging systems, telecom switches, power supplies, heavy equipment, industrial automation, and consumer electronics. The design provides excellent thermal and electrical shielding, ensuring that components are protected from Electro-static discharge (ESD), power surges, and any other environmental factors.

The working mechanism of QMS-052-05.75-L-D-A-K connectors involves a simple, yet effective latching system. As the connector is mated, each contact slides into its respective socket, and once in place, a plastic retention clip snaps into a mating hole, holding the connection securely in place. Upon removal, the clip is released and the connector is disconnected.

This edge-type connector features an integrated wiring harness, enabling the wires to be easily inserted into the connector. The connector is also UL 94V-0 approved, meaning that it is perfectly safe to use in any application requiring such a level of safety assurance. The QMS-052-05.75-L-D-A-K is RoHS compliant, as well.

In summary, the QMS-052-05.75-L-D-A-K mezzanine connector is a highly reliable and cost-effective component, designed for use in a variety of complex, high-density board-to-board interconnects. It is UL 94V-0 approved and RoHS compliant, and is able to provide excellent thermal and electrical shielding for all connected components. Its simple, yet effective latching system ensures that connections are secured, and the integrated wiring harness allows for effortless wiring connection.
