1-644749-7

Rectangular connectors, also known as Headers, Male Pins, are a type of electrical connection found in many types of electronic devices. They consist of an enclosed metal housing with two rows of pins that fit inside the housing. Each pin has a specific purpose within the device, and when the pins are placed in the correct order, the connection between the device and the power or data source is made.

The 1-644749-7 is an example of a rectangular connector and is a two conductor, two row, shrouded header. This style of connector is most often used in point-to-point, or application specific environments where the data and power needs to move between two electrical components and can’t be routed to any other devices. The 1-644749-7 is designed to mate with the popular 1-643570-7 two conductor plug connector. The pins on the 1-644749-7 are spaced at .100” (2.54mm) centers in both rows, making them very compatible with many other types of sockets and PCB boards.

The 1-644749-7 is available in three popular colors – black, green, and white – and measures 1.200” (30.48mm) in length, .100” (2.54mm) in width, and .035” (0.8mm) in height, with a weight of 1.2 grams. The metal housing and pin terminals are made of UL94-V0 plastic for flame retardancy and excellent temperature and environmental usage. The terminals also feature 0.025” (0.63mm) square posts for a secure connection. The mating spring tension can be increased as necessary by changing the contacts to suit the specific application.

The 1-644749-7 is designed for use in commercial applications such as industrial and medical as well as consumer applications such as lighting and automotive. It is also very useful in high-current relay applications. With its metal shield and shrouded back shell, this connector is hi-pot approved for safety, and carries a UL flammability rating of 94 V-0.

The working principle of the 1-644749-7 is fairly simple. When the two rows of pins on the connector are placed into the socket, an electrical connection is made between the power or data source and the device. The metal housing in the background provides a shield that protects against any external interference, and the resilient tabs on the back of the connector ensure that it does not come loose during use.

In conclusion, the 1-644749-7 rectangular connector is an inexpensive, reliable, and oftentimes overlooked purpose built connection between two electrical components. Its size, weight, and ease of assembly make it the perfect choice for many applications. It is available in three colors, and carries UL 94-V0 approval for temperature and environmental stresses.
