71920-402LF

Rectangular Connectors - Headers, Receptacles, Female Sockets

The 71920-402LF, commonly known as a ‘rectangular connector’, is a device designed for connecting electronic signals and power in many applications. It is commonly used in a range of industries like automotive, military, aerospace, and industrial.

The 71920-402LF is an example of a header in the rectangular connector family and is designed for PCB-to-PCB applications. It features a single row of two point contact sockets (polarized and non-polarized) mounted on an array of pins that can be easily soldered onto printed circuit boards. Additionally, it has a 1.5mm header pitch that allows for a more compact design, thereby making it ideal for space-restricted applications.

In terms of connectors, the 71920-402LF is more reliable and efficient compared to more traditional connectors such as screw-type and coaxial connectors. In particular, there is no need for extensive soldering when it comes to assembling this device as it merely requires the insertion of header pins. In addition, its design ensures low contact resistance and higher current carrying capability resulting in a more reliable and robust connection.

As for its working principle, the 71920-402LF works by creating an electrical connection between two components. When one connector is inserted into the other, the contact points of both components come in contact with each other creating a conduction path. The contact points are usually made from zinc or brass, and allow the current to flow from one point to the other. This connection is usually maintained by the force of a spring, which helps ensure that the connection is making good contact. If there is any damage, the spring will ensure the connection returns to its normal state.

Apart from its performance, another advantage of the 71920-402LF is that it is relatively easy to work with. The connectors are designed in such a way to allow for easy assembly and connection to other components. Furthermore, its plug-in connectors make it easy to replace components if required.

In conclusion, the 71920-402LF is an essential piece of equipment for any electrical engineer. The device is capable of making reliable connections with higher current handling capacity compared to traditional connectors and provides overall convenience due to its easy installation. All these advantages make the 71920-402LF an ideal candidate for a wide range of applications.
