Rectangular connectors, also known as headers, male pins, etc., are widely used in instruments, communications, computers, and other electronic products. Such as power supply connection, data transmission, signal control, etc. MTMM-120-15-S-D-685 is a typical rectangular connector header. And in this article, let’s discuss MTMM-120-15-S-D-685 application field and working principle.

Overview of MTMM-120-15-S-D-685

MTMM-120-15-S-D-685 is usually a 1.27mm pitch two-row male header connector for printed circuit boards. It has a total of 120 terminals. Its main feature is a sufficient number of terminals coupled with a normal size. The total mounting height is 15mm. The mating face has a length of 68.5mm, which provides a large installation space and is suitable for bigger motherboards. Its terminals are plated with gold, making it more durable, wear-resistant and corrosion-resistant.

Application of MTMM-120-15-S-D-685

Due to its large number of contacts, MTMM-120-15-S-D-685 has the ability to deliver more reliable power and data signals. As mentioned earlier, it is best suitable for applications such as power supply connection, data transmission, signal control, etc. The typical application of a two-row male header is in the motherboard. It is commonly used to assemble the standard 100-pin power supply contact to the motherboard and connect the peripheral device to the motherboard to ensure reliability.

Working Principle of MTMM-120-15-S-D-685

The main function of MTMM-120-15-S-D-685 is to transmit the necessary power and data signals for electronic devices to realize the desired electronic control functions. MTMM-120-15-S-D-685 is a two-row arrangement of male pins, which will be directly inserted into the female socket with two -row arrangement of contacts. And it is through the press fit of the two sets of two rows of contacts, and the support of the metal shell to ensure the electrical connection between the two.

The two-row female socket of MTMM-120-15-S-D-685 has many sharp contacts, which can bite into the male header, forming a good press fit connection. At the same time, the contact of the male pin is plated with gold, not only increasing its wear resistance and corrosion resistance, but also greatly reducing its contact resistance and ensuring that the voltage and current values can be controlled and stable during transmission. Moreover, the metal shell also ensures the mechanical connection strength between the two devices, so as to obtain the strongest stability.

In short, MTMM-120-15-S-D-685 is the best choice for power supply, signal transmission and control applications. Its contact design and gold plating technology greatly reduce the contact resistance, and the reasonable arrangement of contacts and the metal shell ensure a strong and stable connection during long-term use. With these advantages, MTMM-120-15-S-D-685 can bring advantages in many aspects of the application.
