Rectangular Connectors - Headers, Male Pins, 4-102978-0-26 Application Field and Working PrincipleRectangular connectors, also known as headers and male pins, are essential components of electronic port architectures. As a reliable connection interface, the 4-102978-0-26 can provide advanced personalized solutions for certain requirements. Understanding the application field and proper usage of this connector are important for a successful connection. Application Field The 4-102978-0-26 rectangular connectors come in different styles and dimensions, and they can be used for various applications that require a reliable and efficient connection. This type of connector is commonly used in power supplies, computers, and communication systems, such as the USB port, FireWire, and HDMI. It is also capable of providing a connection between a PCB board and its external electrical components, such as LEDs, transistors, and zener diodes. Additionally, this type of connectors can be employed in the automotive, telecommunications, and consumer electronics industries. Working Principle The 4-102978-0-26 rectangular connector is a two-piece device consisting of a header and a socket. Both the header and the socket have a 6-pin configuration. The header features three pins in the center, with a larger pin above two smaller pins. The socket also has three pins in the center, however, the larger pin is seated between two pairs of small pins. The header is soldered onto a PCB board, while the socket is attached to a cable or control panel. When the socket is inserted into the header, the middle pins align and make contact, while the larger pin provides a local power supply. This type of connector is usually mated with a lock slot or a cord grip that ensures a secure connection. Conclusion The 4-102978-0-26 rectangular connector is a reliable and efficient port solution that can be used in different applications and industries. Its versatile design and excellent performance makes it an ideal choice for power supplies, computers, and electrical components.
