QTE-042-03-H-D-DP Application Field and Working PrincipleRectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) are a common type of interconnect device used for connecting printed circuit boards, cables, and flexible printed circuits together, for both power and data connections. The QTE-042-03-H-D-DP is one such type, and is particularly well suited for high-speed, high-density applications.OverviewThe QTE-042-03-H-D-DP is a surface-mounted, board-to-board rectangular connector with contacts arranged in a dual row. This connector features a shrouded design and a keying system to prevent mismating of the two pieces. The connector is made from a high-temperature, thermoplastic material, with stainless steel contacts and a gold finish. It is also available in a flexi version which allows for flexing in the plane of the PCB.The QTE-042-03-H-D-DP has a field-proven contact system with a double beam construction which provides reliable electrical contact even when subjected to vibrations and shock. The contact system is rated for 3A, up to 6A of current and 350V. It also features an insulation resistance of 500MΩ and an operating temperature range of -40°C to +105°C.Application FieldThe QTE-042-03-H-D-DP connector can be used in a variety of applications, including automotive, aerospace, medical, industrial, appliance, and commercial products. Its shielded design and high signal integrity makes it ideal for high-speed, high-density applications that require reliable electrical connection. In addition, the connector is suitable for board-to-board and backplane applications in which increased space savings is a priority.Working PrincipleThe QTE-042-03-H-D-DP connector utilizes a dual beam spring contact system to ensure a reliable electrical connection. The contact system is designed to have an operating life of at least 1,000 mating/un-mating cycles. The connector also features a pair of indexing pins which can be used to ensure correct alignment of the mating boards.When the two halves of the connector are mated together, the contacts are mechanically coupled through a series of springs. The male contacts make contact with the female contacts, which provides the electrical connection between the two boards. The connector also includes a stainless steel shell which acts as a shield and provides additional mechanical strength. ConclusionThe QTE-042-03-H-D-DP is a rugged, high-speed, dual row, board-to-board, rectangular connector. It is designed for high-density applications and has been proven to provide reliable electrical connection even under harsh conditions. Its shrouded design and keying system make it ideal for applications in which increased space savings are a priority. The connector is suitable for use in automotive, aerospace, medical, industrial, appliance, and commercial products, and is rated for 3A, up to 6A and 350V.
