DF18B-40DS-0.4V(81) Application Field and Working PrincipleThe DF18B-40DS-0.4V(81) is a unit that belongs to a category of connectors called Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board). This type of connectors is suitable for applications involving the connection of multiple boards such as those found in computers and communications equipment. The internal construction of this connector type is based on a structure of single or double rows of rectangular pins that make electrical contact with respective sockets along an edge. In this case the DF18B-40DS-0.4V(81) features a double row of 40 pins spaced at 0.4V, (81) pins in total. This connector type is designed for applications that require high quality signal and power transfer, and can be used to connect a range of different multipoint signals and/or powers. Each contact of the connector is rated to carry up to 3A currents and working voltages of up to 48V.The working principle of the DF18B-40DS-0.4V(81) is simple. It is designed to provide a reliable connection between two circuits by making an electrical contact between each of the pins and sockets of the rectangular array. This contact point will provide a good electrical connection between the two circuits, ensuring that reliable data transfer and/or power delivery takes place. The contact points are also designed for easy assembly and disassembly, allowing connectors to be connected and disconnected quickly and easily.Due to the design of the DF18B-40DS-0.4V(81) it is particularly suitable for applications requiring high levels of reliability. This connector type also has a good resistance to shock and vibration, making it especially suitable for use in harsh environmental applications where low levels of vibration and shock are generally present. Additionally, this connector type has been designed with low reflection losses and crosstalk levels, resulting in a more reliable data link that allows for longer transmission distances than conventional connectors.It is also worth noting that the DF18B-40DS-0.4V(81) is one of the most commonly used connectors in the mezzanine board-to-board connector industry, due to its robust design and ease of installation. It is commonly found in applications where signal integrity is critical, such as in communication and networking systems. As such, it is suitable for a wide range of applications and can provide an ideal solution for any system where reliable signal transfer is a must.
