QMS-052-06.75-L-D-A

Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) play a key role in connecting the host board and daughter board in modern electronic circuit designs. One of the most common types of these rectangular connectors is QMS-052-06.75-L-D-A. It has been widely used in various electronic systems for its superior performance and excellent reliability.

QMS-052-06.75-L-D-A is an edge-type, mezzanine-style rectangular connector with a 2.5mm pitch. It comes with two rows of 6.75mm leaded contacts and can be soldered into both the top and bottom surfaces of a PCB, enabling it to be installed in a wide variety of mounting options. The connector is compliant to MIL-STD-1560E, so it is highly reliable and suitable for use in demanding military and industrial applications. It also complies with RoHS 2.0 and has an operating temperature range of -65°C to +160°C.

QMS-052-06.75-L-D-A features a metal slide lock which securely fastens the mated connector and protects it from external damages, and also makes the connector panel mountable if necessary. Durability-wise, this connector has been tested to meet mating and unmating requirements of 500 cycles, making it a good choice for those applications that require frequent connection/disconnection. It also features a compact design, making it an ideal choice for space-constrained applications.

In terms of its working principle, QMS-052-06.75-L-D-A makes use of a pin-and-socket design. The male and female connectors are both double-sided, each featuring 9 gold-plated pins that make contact with their corresponding sockets. The pins are arranged in two rows with 6.75mm leaded contacts. When the male and female connectors are mated together, the pin and socket contact forces the two connectors together, resulting in an electrical connection between the two, thus enabling the flow of power and signal through the connector.

The QMS-052-06.75-L-D-A connector is mainly used in applications where a reliable and stable connection between the host board and daughter board is required, such as in communication devices, automotive and aerospace industry, test and measurement equipment, computer/server motherboards, and low-power DC circuits. This connector can be used with a range of circuits and cable types, and can also be installed in various mounting options, which makes it a highly versatile and reliable connector for various applications.
