Rectangular Connectors - Headers, Male Pins are designed to join two or more circuits, or to enable the connection of a circuit with a device, like an LED or a motor. The 644751-9 connector is a popular product in the family of rectangular connectors, and it offers significant advantages, both in terms of cost and performance.
Application Field
The 644751-9 connector is primarily used in industrial and commercial applications for the interconnection of wire harnesses in PCBs, routers, servers and similar applications. The product can also be used in a wide range of audio/visual applications, as it has been designed to have low cross-talk and low power losses. In addition, it is suitable for use in communication systems, such as VoIP, Gigabit Ethernet and FTTP, and it can also be used in automotive applications.
Working Principle
The 644751-9 performs its basic function through the establishment of physical contact between the two facing surfaces in the connector. It is designed with a small, low-profile profile, making it suitable for applications where space is limited. The electrical connection is achieved through the use of a male pin on one side and a female header on the other side. The two facing surfaces are designed to accommodate the pins and headers, and the device relies on physical contact between the two sides to establish the electrical connection.
The device offers significant flexibility, as the male pin and female header both have their own separate ground connection, allowing for the connection of different circuits in a single connection. The device also offers protection against overheating, due to its insulating material and air-tight enclosure. In addition, the device also features a locking mechanism, which prevents accidental disengagement of the connector.
The 644751-9 connector is designed for easy installation and maintenance, with a secure snap-lock mechanism and a small, low-profile design. The device also features a number of design features to ensure reliable performance, such as an increased contact area between the male pin and female header, and a durable and corrosion resistant material.
