Rectangular Connectors – Arrays, Edge Type, Mezzanine (Board to Board)

Rectangular connectors, Arrays, Edge Type, and Mezzanine (Board to Board) are all types of connectors that are used to connect electronic circuits. These connectors come in a variety of sizes, shapes, and configurations. The DF17B (4.0)-20DS-0.5V (57) application field and working principle is one particular type of a rectangular connector that serves multiple purposes.This particular type of rectangular connector is designed to mechanically and electrically connect two or more printed circuit boards on a PCB (Printed Circuit Board). This type of connector is used when it is not possible to make the connection with a standard pin-and-socket arrangement. It is usually used when the size of the board-to-board connection does not allow sufficient space for a pluggable connection. This type of connector is also advantageous when the need for multiple board-to-board connections with quick installation and removal is required.The application field of the DF17B (4.0)-20DS-0.5V (57) rectangular connector includes applications in automotive systems, consumer electronics, industrial systems, communications, and computer systems. It is suitable for high-speed applications, such as high-speed data transmission systems, industrial signal transmission, and consumer electronics. The DF17B (4.0)-20DS-0.5V (57) connector is a 7-way, 0.5mm pitch connector. This connector is compliant with the JEDEC standard and is made from a high-temperature thermoplastic (PA6T/6) material. It has a mechanically robust design with an operating temperature range of -40°C to +125°C.The working principle of the DF17B (4.0)-20DS-0.5V (57) connector is relatively simple. The pin and socket system of the connector allows for a firm connection between the two boards when mated correctly. The connectors are secured with a snap-fastening mechanism that ensures that the pins are firmly in place. This is why the DF17B (4.0)-20DS-0.5V (57) connector is ideal for applications that require quick installation and easy removal.The DF17B (4.0)-20DS-0.5V (57) connector also provides high current carrying capacity and good electrical performance. The contact force is designed to ensure a good electrical and mechanical connection, and the contact resistance is low. This ensures that the connection is stable and reliable. The connector also complies with EMC (Electromagnetic Compatibility) and ESD (Electrostatic Discharge) requirements.In conclusion, the DF17B (4.0)-20DS-0.5V (57) connector is a reliable, flexible, and cost-effective solution for applications that require a board-to-board connection. It is suitable for a variety of applications and has good electrical and mechanical characteristics. It is also easy to install and can be quickly removed, making it an ideal choice for applications that require multiple connections with a quick installation and removal.
