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

The QFS-016-04.25-H-D-DP-PT4 is a type of rectangular connector array specially designed for mezzanine, edge-type connections. It is most often used in the production of devices and equipment with limited mounting space. For example, these connectors have been used in industrial automation, robotic control systems, medical imaging equipment, multimedia equipment and other applications.

Application

Designed for high-density, edge-style Board-to-Board applications, these connectors are ideal for densely-packed applications where the use of multiple individual board-to-board connectors is not feasible. The QFS-016-04.25-H-D-DP-PT4 also features a variety of pinouts to meet requirements for custom applications. This connector includes sixteen differential channels, four high current single-ended channels, one power supply channel and a user-defined high yield female connector.

Design

The QFS-016-04.25-H-D-DP-PT4 is designed to be compatible with many existing industry standards, such as the popular VESA FPD-Link III standard, USB3.0, HDMI and Mini-DisplayPort. It is designed to provide high quality, low-cost interconnectivity solutions for use in a variety of applications. The pass-through configuration allows for easy connection to existing or future devices.

Features

The QFS-016-04.25-H-D-DP-PT4 offers several features that make it ideal for board-to-board applications. These include a 0.8mm pitch, high current support up to 4A per differential channel, high-density, low noise design, and superior signal integrity across all channel types. It also allows for data speeds up to 5.3 Gbps per differential pair and supports up to 4A of power per power signal.

Working Principle

The QFS-016-04.25-H-D-DP-PT4 works similar to other types of board-to-board connectors, however it achieves higher data transfer rates by leveraging differential coupling to eliminate crosstalk and reduce electrical noise. Each differential pair is connected to the mating side through the connector’s pins and protected from environmental conditions (such as dust, water and humidity) by a layer of protective insulation. On the plug side, each pair of pins are assembled to terminal strips that connect them to the circuit board’s transmission lines, improving their electrical performance and allowing higher transmission speeds with improved signal integrity.

Conclusion

The QFS-016-04.25-H-D-DP-PT4 is a versatile and cost-effective solution for high-density Board-to-Board applications spanning a variety of industries. It is designed to meet the needs of environments with limited space, higher data rates, higher power requirements and improved signal integrity. Its design features a wide variety of pinouts and easy-to-use, differential-coupled channels, allowing for a variety of applications.
