Rectangular connectors are widely used in a variety of applications, providing electrical connections in a wide variety of electronic products. The 155220-6203-RA is a rectangular connector, also known as a Header, Male Pin, which provides an electrical connection for various applications. This guide explains the application field and working principle of the 155220-6203-RA.
The 155220-6203-RA header is mainly used in electric control systems. Generally speaking, it is used to connect different circuit boards or circuit systems of the same system through the header. The header has a large number of pins, which can output signals and vectors after signal processing. Thus, it can realize the communication process between different circuits in the system, and output the signal at the same time.
In order to prevent wrong insertion in the application process, key grooves on male and female headers are designed. The male header has 2 key grooves, and the female header has a corresponding opposite position. When two headers are connected, the key grooves are aligned to ensure accuracy in application. This eliminates the problem of misalignment in the system.
The advantages of the 155220-6203-RA header mainly include energy saving, good insulation performance, and reliable connection. Compared with other types of connectors, this header has a smaller contact resistance and lower power consumption. The small contact resistance can help improve the stability of the circuit. Moreover, its insulation performance is better because of its shell made of good insulating materials. The solid welding feet also increase the reliability of its electrical connections.
The working principle of the 155220-6203-RA header is relatively simple. When connected, the press-in pins are inserted into the female header, and the signal is transmitted between them. At the same time, the conductive contacts inside the female header are in good contact with the press-in pins, and the signal is output to realize the transmission of the signal. After the transmission, the press-in pins are pressed to a certain depth, thus ensuring the transmission and output of the signal.
Using 155220-6203-RA header can effectively reduce the size of the circuit, as well as the energy loss in the circuit. Moreover, reliable electrical connections ensure the safety and reliability of the circuit. The good insulation performance helps eliminate the problems of signal interference and electrical leakage. As a result, the 155220-6203-RA header is widely used in electric control systems and circuit applications.
