Rectangular Connectors - Headers, Receptacles, Female Sockets: 399-13-121-10-003000 application field and working principleRectangular connectors consist of two parts, a header and a receptacle. A header is a plug that is inserted into the back of a computer to make a connection between a device like a graphics card or CPU and the motherboard. The receptacle is a socket that the header plugs into. A female socket is essentially the same as a receptacle, but it is designed to accept the male connection end of a cable or a header.The 399-13-121-10-003000 rectangular connector is a header and receptacle designed for high frequency digital and analog signals. This type of rectangular connector is commonly used in applications such as telecom/datacom equipment, high power amplifiers, and industrial control systems.The header is comprised of two rows of pins arranged in straight rows. Each pin can carry a different signal, from digital logic signals and variable power levels to differential pairs. The pins are plated gold over nickel, which helps to ensure a reliable electrical connection.The receptacle is designed with two rows of sockets to accept the pins of the header. The contact surfaces are plated gold over nickel, which helps to eliminate electro-migration and improves connection integrity. The receptacle also has two mounting ears that can be used to mount it to a surface or a panel.The working principle of the 399-13-121-10-003000 is relatively simple. When a header is inserted into the receptacle, the pins of the header make contact with the sockets of the receptacle. This creates an electrical connection between the two parts. When the header is removed, the connection is broken.The 399-13-121-10-003000 can also be used for power connections. The pins of the header are designed to carry different voltages and can be used to power various devices. The receptacle also has two mounting ears, which can be used to mount the connector to a surface or a panel and provide additional stability for power connections.The 399-13-121-10-003000 is designed to be reliable and durable, making it ideal for applications such as telecom/datacom equipment, high power amplifiers, and industrial control systems. It is capable of handling high frequency digital and analog signals, providing a reliable connection. Its gold over nickel plating helps to ensure a reliable electrical connection and its two mounting ears provide additional stability for power connections. The 399-13-121-10-003000 is an ideal choice for reliable and high-performance rectangular connectors.
