Rectangular Connectors - Headers, Male Pins

N3428-L202RB Application Field and Working Principle

Rectangular connectors, also known as headers, male pins, are important components used in electronic and electrical connection systems. The N3428-L202RB is one of the most widely used varieties of such connecting systems. This type of connector is suitable for a wide range of applications, including computer signal line connection, electrical connection circuit connection, and even medical machine connection.The N3428-L202RB is a high-performance rectangular connector designed for use in harsh environments and with high vibration levels. The cable connector is made from nickel-plated copper alloy, making it resistant to corrosion and oxidation, and its architecture allows for good power performance and strong signal transmission. Additionally, the N3428-L202RB series connectors offer 360° shielding for excellent electromagnetic interference protection. To attach the N3428-L202RB to a printed circuit board, first, the PCB must be drilled with the corresponding size hole for the connector. Models between 2 and 10 contacts are available with pitched slots of 4.3mm, 4.9mm and 5.8mm between the contacts. It is also possible to get a version with a soldering eyelet instead of a plug. The soldering eyelet provides a more reliable connection and is suitable for higher frequency transmission. Once the hole has been drilled in the PCB, the inserting must be completed. An automated insertion machine is commonly used for this operation, but manual insertion is also possible. The connector can then be fixed to the board with M2.5x4mm screw or M2.5x5mm screw depending on the hole size. The structure of the N3428-L202RB consists of three components: the shell, a conductive piece and the insert portion. The shell can protect the plating and can be mounted directly from the bottom or the top of the PCB. The conductive piece is connected to the motherboard and the connector itself; it also acts as a shield to reduce the radiation interference. Finally, the insert portion is inserted into the cable port and can be machined according to customer\'s requirement.In summary, the N3428-L202RB series of connectors are most suitable for applications related to computer signals, electrical connections, and even medical machines. They feature good power performance and strong signal transmission, as well as 360° shielding for excellent electromagnetic interference protection. They can be inserted manually or by automated machinery, and fixed with M2.5x4mm, and M2.5x5mm screws. The components consist of a shell, a conductive piece, and an insert portion.
