NPPN022AFCN-RC is a rectangular connector more commonly known as a header. This type of connector is primarily used to make electrical and mechanical connections between two devices, as well as being used in the manufacturing industry for testing, inspecting and identifying components. There are many types of connectors, however NPPN022AFCN-RC is a specific type of header used to connect a motherboard to a card edge connector. The header is positioned on the board and the card is inserted into the header.

NPPN022AFCN-RC is a narrow, up-suited and pitch-controlled header made from brass bodies with gold plating. It has a 7.5mm pitch, 22 contacts with a nominal current rating of 2A. This particular connector features a lock-in insertion structure with right angle with a 2.0mm diameter contact.

Application Field

The NPPN022AFCN-RC is used in a variety of applications due to its size and current rating. The main use is for connecting a motherboard to a card edge connector in computer motherboards. This connection is used to facilitate the connection of additional devices such as memory cards, HDD, FDD, PCI cards. It can also be used in industrial automation, medical devices, test and measurement, and telecommunications.

Working Principle

The working principle of the NPPN022AFCN-RC is as simple as selecting the right parts and inserting them correctly. The board-level header is inserted into the motherboard face down. The pin side is then mated with another board edge connector. The mechanical locking mechanism featured in the header helps to ensure that the connection remains in place once it is made. This same mechanical locking mechanism also prevents the possibility of the connector coming undone when the boards are separated.

Once the header and card edge connector are mated, the contacts are disengaged allowing for the flow of electrical signals. This is done via the reverse side of the card edge connectors. The contacts, when engaged, create a metal-to-metal contact which enables the electrical flow. Upon disengagement of the connectors, the contact points open once again ensuring that the flow of electricity stops.

The NPPN022AFCN-RC is a reliable and versatile rectangular connector capable of making reliable and efficient connections between a motherboard and card edge connectors. Its ease of use, small size and high current ratings make it a popular choice for many industrial and consumer applications.
