The QSE-040-01-F-D-A-L-K-TR is a rectangular connector array, edge type, mezzanine (board to board) product from a leading manufacturer in the industry. This specialty board-to-board connector uses a standard 5.08 mm (0.2") pitch spacing and is designed to carry high-speed data and power signals between two electronica boards. The diversified QSE-040-01-F-D-A-L-K-TR connectivity system offers robust signal and power solutions available with single or multi-level connectors, contact sweeps, and a variety of contacts in contact pitches. This combination of features provide the system flexibility for use in a wide variety of industrial, computer and telecom applications.

The QSE-040-01-F-D-A-L-K-TR connector array consists of a single row of 20 contacts with a 4 mm pitch. The four-position keying allows for two AC power contacts, two high-speed signal contacts, and twelve data contacts. The system is designed for PCBs with standard FR-4 material and 1.6 mm thick layer 2 finish. The connector contacts are made of solid copper pins with gold plating, and the board-to-board interface is made of a high-strength, low-profile aluminum alloy.

The QSE-040-01-F-D-A-L-K-TR’s four-part design meets application requirements for better signal integrity. The first part of this system is the housing which is made of a high-strength aluminum alloy. The two-part housing acts as a barrier to prevent any dust or dirt from entering the board, ensuring reliable connections and long-term service life. The second part of this system is the terminal pin, which are precision machined from solid copper pins that are designed to resist oxidation and corrosion. Thirdly, the board-to-board interface allows for good electrical performance, while the fourth part, the helical springs, provide ground contact and reduces the number of cables needed for installation.

The QSE-040-01-F-D-A-L-K-TR’s efficient design helps minimize contact force, which makes installation and removal easier and provides reliable operation. Thanks to its solderless, press-fit termination applications, no extra tools are typically required for installation. Additionally, the connector’s four-position keying reduces potential for accidental mismating. Furthermore, with its rugged housing and durable contacts, this system has superior environmental seals and can protect against dust, extreme temperatures, and atmospheric pressures.

The QSE-040-01-F-D-A-L-K-TR’s range of applications and working principles make it one of the most effective rectangular connectors on the market. It is an ideal choice for use in industrial electronics, computer, telecom and industrial control systems, given its high-speed and power capabilities, as well as its robust soldering, press-fit and multiple-level connections options. The multiple contact pitches and keying system also increase the flexibility of the product and make it suitable for different combinations of power, signal and data applications. The QSE-040-01-F-D-A-L-K-TR is compliant with international standards such as ISO 9001, RoHS, and UL/CSA standards, and is designed to meet the quality and performance standards necessary for long-term operation and reliability.
