RECTANGULAR CONNECTORS - HEADERS, MALE PINS, LTMM-122-01-G-D-SM-P application field and working principle

Rectangular connectors - headers, male pins are one of the most popular connectors in the electronic industry, and LTMM-122-01-G-D-SM-P is the model of this type connectors. It has various application fields and its working principle can be divided into a few basic steps.

Application Field

LTMM-122-01-G-D-SM-P is widely used in telecommunications, data transmission, consumer electronics, measuring instruments, medical equipment and other industrial automation systems. It applies 2.0mm PCB header technology and is a widely used device for mounting printed circuit boards (PCBs). Its compact size requires less space than other connectors, and its low cost and high simplicity make it ideal for low-end applications.

Working Principles

Working principles of the LTMM-122-01-G-D-SM-P can be divided into paste printing steps, square pins assembly, side printing and electrical operation test. During paste printing process, the solder paste is printed on the PCB surface with high precision. Then, the square pins of the connector should be interconnected with the terminal zone of the printed PCB board accurately. After that, side printing is necessary to connect the housing to the board by screws or rivets and then solder the pins to the PCB.Finally, electrical operation test is carried out in order to make sure the quality of the product. During this test, the product is working in different pressure, electric current, wattage etc. to examine the performance. After confirming the performance parameters are within the standard, the product will be sent to customers.

Conclusion

LTMM-122-01-G-D-SM-P is a type of rectangular connectors - headers, male pins, which is widely used in electronics, telecommunications, medical equipment and other industrial automation fields. Its superior performance makes it suitable for low-end applications. In addition, its working principle can be divided into paste printing, square pins assembly, side printing and electrical operation test. Finally, it also should pass electrical operation test before delivery to customers.
