QFS-026-04.25-L-D-PT8 - Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board)

Rectangular connectors are used to connect two or more circuits. Commonly used in many industries, rectangular connectors come in various sizes and types, which are designed to meet the requirements of various applications. The QFS-026-04.25-L-D-PT8 is such a type of rectangular connector, designed for use in array, edge, and mezzanine (board-to-board) applications. In this article, we’ll explore the application field and working principle of the QFS-026-04.25-L-D-PT8 connector.

Application Field

The QFS-026-04.25-L-D-PT8 connector is designed for two recessed 25-pole, two-row, zero-footprint mezzanine style arrays, edge type, and board-to-board applications. It is applicable for applications with speeds of up to 10 Gbps. The contacts are 0.025-inch and the pin is gold-plated for improved resistance against corrosion. The connector has an operating temperature range of -25°C to +85°C.

The QFS-026-04.25-L-D-PT8 connector is available with three different pitch sizes: 0.050, 0.100, and 0.156. This makes it suitable for applications that require a wide variety of pitch sizes. It also has an additional 8-pole space for high speed signaling. The connector is available in a large variety of mating pairs, making it suitable for a wide variety of applications.

Working Principle

The QFS-026-04.25-L-D-PT8 connector utilizes a simple mezzanine-style array contact system. The connector features two recessed versions and a choice of three different pitch sizes. It uses a gold-plated contact system that provides enhanced resistance to corrosion. The contact system consists of a spring-loaded contact located in the connector housing, which is mated to the mating contact in the other connector. The spring-loaded contact makes electrical contact with the mating contact when the mated connectors are pushed together, thus creating an electrical connection. The contact system also provides a firm connection that does not move or vibrate when connected.

The connector also features a snap-in mounting mechanism. This allows the connector to be easily mounted in panels or other surfaces without the need for additional hardware. The locking system ensures that the connector stays firmly in place and does not disconnect. The contacts also feature a positive lock to prevent them from becoming dislodged during use.

The QFS-026-04.25-L-D-PT8 connector is available in two recessed styles (straight and angled) and three different pitch sizes. The connector is ideal for applications that require a reliable, robust, and compact connection for high speed signaling. It is suitable for use in a variety of applications, including array, edge, and mezzanine (board-to-board).

Conclusion

The QFS-026-04.25-L-D-PT8 is a compact, reliable, and robust rectangular connector. It is designed for applications with up to 10 Gbps speeds, and it is available in two recessed styles and three different pitch sizes. The connector features gold-plated contacts that provide improved corrosion resistance. It also has a snap-in mounting mechanism for easy installation and a positive lock mechanism for secure connections. The QFS-026-04.25-L-D-PT8 is suitable for use in array, edge, and mezzanine (board-to-board) applications.
