The QRM8-052-05.0-L-D-A belongs to the category of rectangular connectors, specifically Arrays, Edge Type, Mezzanine (Board to Board). It is a reliable form of electrical connector used to facilitate the connection between two printed circuit boards. It functions as a bridge, linking on board circuits to off board circuits, and propagating signals from either end.

This particular connector is characterized by several features, such as its board-to-board pitch of 5.2 mm, a “L” with 0.40 mm tail pin, 161 mounting holes, surface mount type and dimensions of 21.8 x 21.8 mm. Additionally, it has a 40-pin vertical stack height, which is ideal for high volume applications, where dimensions are crucial. It also has a plastic connector housing, with a black liquid crystal polymer, which provides superior shielding against vibrations and impacts.

The QRM8-052-05.0-L-D-A is typically used in a multitude of applications, such as wire-to-board connectors, communication systems, power supplies, medical equipment, consumer electronics, and many more. It is an ideal choice for low-frequency and low-noise applications, as it has a wide frequency range of DC to 6GHz and operates within a VSWR of 1.1 Maximum (DC to 4GHz). Furthermore, the connector has excellent shielding capability, with an insertion loss of 0.2 dB (maximum) at 1GHz, and excellent return loss of 40dB (minimum) at 8GHz.

In regards to its working principle, the QRM8-052-05.0-L-D-A is straightforward. It has a total of 40 signal contacts, which are constructed from tin plated brass, and housed within the plastic body. These contacts allow for quick and easy interconnection between the two printed circuit boards, which is achieved via a simple pin-in-hole design. Additionally, its tail pin provides a secure and reliable contact between the two boards at all times.

The QRM8-052-05.0-L-D-A has a number of advantages in terms of reliability and performance. Notably, the plastic body ensures sealed protection against dust, dirt and other environmental elements, meaning that the connector is highly resistant to corrosion. Additionally, the high quality construction of the contacts, along with its small size and light weight, make it a perfect choice for space-restricted applications. Furthermore, it has a rated current of 1.5A, meaning that there is no need for an extra power cable.

Overall, the QRM8-052-05.0-L-D-A is an excellent choice for a range of applications, due to its reliable connection and superior performance. It is a cost-effective solution for linking two PCBs, and its small size means that it can be used in a variety of settings. Furthermore, its reliable design ensures a long-term connection, and its shielding capability means that it can easily provide noise protection and EMI/RFI protection. All of these features make it a great choice for wire-to-board connectors, communication systems, power supplies, medical equipment, and consumer electronics.
