QFS-052-02-H-D-RA-PC4, part of the rectangular connector - arrays, edge type, mezzanine (board to board) family, is part of a system of contact connectors. It is a two-row, right angle type of adapter that is used to provide a cost-effective and simple connection of two printed circuit boards by way of a two-row system.

The right angle shaped QFS-052-02-H-D-RA-PC4 is effective in providing power between two or more boards with high signal integrity. The right angle style makes it possible to reduce the length of the cable, enabling an effective use of space within confined systems. It also provides a higher packing density of line cards, in which cables may be routed between the two boards. As a result, miniaturization of devices is achieved with efficient use of board space.

QFS-052-02-H-D-RA-PC4 has a rated current of 4.0 A and operating temperature range up to -30C to +85C. It supports high-up time voltage (V_hup) up to 5.0 V and low-down time voltage (V_ldown) up to 0.8 V, and a high dielectric strength of 250 VAC RMS. This connector is also available in three different pitches, depending on the application: 0.050" (1.27 mm), 0.100" (2.54 mm), and 0.200" (5.08 mm).

QFS-052-02-H-D-RA-PC4 has two main working principles. First, the connector features a pair of spring-type contact structures, which ensures continuous electrical connection between the two boards and thus provide efficient power transfer. A second principle is the efficient clamping of the boards due to the profile of the front side of the device. By tightening the screws, tension is applied both between the edge of the boards and the connectors, and within the connector itself. As a result, the board is held firmly between the two members of the connector, providing added protection against vibrations or vibration-active assemblies.

QFS-052-02-H-D-RA-PC4 is an effective and reliable serial board mating system for applications that require a small form factor. It has a wide variety of applications in communication equipment, displays, consumer electronics, audio systems, instrumentation, and other consumer electronic equipment. With its cost-effective, high signal integrity and space saving design, the system ensures continuity of performance even in demanding environments.
