QFS-026-04.25-L-D-PC4

QFS-026-04.25-L-D-PC4 is a type of connector in the category of Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board). Edge Type connectors provide a mechanical and electrical connection between two printed circuit boards (PCBs), and offer a wide variety of options, such as different row counts, termination types, and contact positions. QFS-026-04.25-L-D-PC4, specifically, is a mezzanine connector with 25 positions in four rows with a contact pitch of 0.025 inches (0.635 mm). This connector has a low profile to fit in tight spaces, and has a gold plated contacts with a D type shrouded shell. The peak temperature of the connector’s male insulator body is 135°C. QFS-026-04.25-L-D-PC4 is typically used for data communication and signal transmission applications, where its compact density and high reliability are needed. The connector can also be used in other types of applications where mating and space are key considerations, such as industrial, instrumentation, and consumer electronic products. QFS-026-04.25-L-D-PC4 works through the press-fit contacts. These contacts feature a tail section for easy insertion into the edge of a printed circuit board (PCB). The contacts are then locked into position with the integrated boardlocks which are actuated by the two sides of the connector. To guarantee stability, the top and bottom of the contacts are also stablilized by the flanges on the mating connector. When the connectors are mated, the contacts make contact with each other, creating an electrical connection, and thus allowing signal and power transfer between the two opposite boards. The contact force needed to create this connection is around 2.3 lbs. The QFS-026-04.25-L-D-PC4 uses high reliability contact designs that are rated for up to 1,500 mating cycles. The contacts are compliant to IEC 60603-2-2 standard for current carrying capacity, flammability, and salt spray resistance, and meet UL 94 standard for flammability test requirements. The connector also meets the IP67 and IP68 standards for environmental protection. Overall, the QFS-026-04.25-L-D-PC4 is a robust and modular connector design that is suitable for a variety of data communication and signal transmission applications, offering a high-density connection in a compact size.
