IntroductionThe QFS-104-02-H-D-RA is a rectangular connector array of Edge Type, Mezzanine (Board to Board) that is used for diverse electrical applications. This type of connector offers a reliable, efficient and cost-effective solution for interconnection between circuit boards with wide range of possible uses.Application fieldCommon applications of the QFS104-02-H-D-RA include computer and electrical systems, consumer products, automotive, medical and aerospace design. It is a widely-used product in both large-scale industrial and small-scale applications due to its compact size, robust construction and low cost.The QFS104-02-H-D-RA is commonly used as an interconnection in high-performance circuit boards for a wide range of electronic applications, such as the connection between an external electronic system and an internal board used as a gateway. It is also frequently used for data transmission between two printed circuit boards (PCBs) in order to transfer data, power, and control signals.The QFS104-02-H-D-RA connector array also finds use in embedded system design due to its compact size. This is because the connector array can be mounted on the limited space of a PCB with a minimum of effort.The QFS104-02-H-D-RA is also suitable for use in a wide range of environments commonly found in outdoor applications, such as dust, humidity, vibration, and extreme temperatures.Working principleThe QFS104-02-H-D-RA connector array is composed of several vertical and horizontal rows of contact pads. The contact pads are arranged in a staggered pattern in order to maximize contact reliability and minimize electrical resistance. A variety of materials, such as gold and copper, are used for the contacts. The contact pads are held in place by springs located underneath the contact pads. This ensures a secure connection between the contact points and the circuit boards.The QFS104-02-H-D-RA also has a protective plastic housing to provide environmental protection for the contact pads. The housing is also designed to reduce crosstalk across the connector as much as possible by preventing potential damage to the contacts from airborne contaminants.ConclusionThe QFS104-02-H-D-RA is a widely-used and versatile connector array of Edge Type, Mezzanine (Board to Board) that is suitable for a large number of applications connected to circuit boards. Its compact size and robust design make it a cost-effective solution for interconnecting two separate PCBs with data, power and control signals. The connector array also includes a protective housing for added environmental protection and to reduce crosstalk.
