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

The QMS-032-05.75-L-D-K-TR is a type of board-to-board rectangular energy connector, intended for application in a range of cabled system projects in aerospace and defense oriented industries. It features a very small size, compliant with MIL-STD-1957 specifications, and supports up to two shielded twisted pairs. This product is available in configurations with a polarized Key Tab (L) oriented along the edge, with a tin over nickel plating finish.

Principle of Operation

The connector operates on the principle of per-contact impedance matching. It consists of two mating components - a male plug and a female jack, each equipped with several pins and corresponding sockets. When connected, small gaps between the pins and the sockets allow electrical energy to flow between the two components, while the per-contact impedance matching ensures that the amount of energy passing through one contact is the same as the amount of energy passing through all other contacts in the array.

Application Field

The QMS-032-05.75-L-D-K-TR connector is mostly employed in applications which require a small size and good electrical characteristics. Its application field includes, but is not limited to, signal transmission in aircraft avionics, portable electronic units, satellite communication systems, medical equipment, robotics, automation systems, and military projects.

Conclusion

The QMS-032-05.75-L-D-K-TR connector is an innovative product for aerospace and defense oriented industries. It features a miniature size, compliant with MIL-STD-1957 standards, with two shielded twisted pairs and a solder termination with tin over nickel plating. It operates on the principle of per-contact impedance matching, and is applicable in a range of projects which require a small size and good electrical characteristics.
