D-Sub connectors are one of the most widely used connectors in electronics and have a wide range of applications. The DCMC25H3SJA197 is a type of D-Sub connector and this article aims to provide an overview of its application field and working principle.

Overview

The DCMC25H3SJA197 is part of the Holtek\'s DCMA series of D-Subminiature connectors. It is a type of male connector with a 25 way size. This male connector has a height of 3.96mm and it is equipped with right angle through hole plating on the PCB.

Application Field

The DCMC25H3SJA197 is mainly used in applications such as data communication, audio application, machine control systems, testing equipment and electronic device control.

Due to its size and low-profile design, this type of D-Sub connector is perfect for use in densely populated electronic systems, where space is a premium. It is also well suited for applications that require reliable signal integrity, such as high-speed data communication systems. Since it is a board-to-board connector, it can also be used for inter-connecting two or more PCBs in order to create more complex systems.

Working Principle

The DCMC25H3SJA197 is a type of solder terminal connector with an integrated contact. The contacts are made from brass and are equipped with gold plating on the surface. This gold plating provides increased electrical resistance and ensures good signal transmission between the board and the connector.

The contact is connected to the board with solder. The outer shell of the connector is made from plastic and provides additional protection for the contacts. The connector also has a locking mechanism, which ensures that the connector stays securely in place even when subjected to shock and vibration.

Conclusion

The DCMC25H3SJA197 is a type of D-Sub connector with a low-profile design, which makes it suitable for a wide range of applications. It is mainly used in data communication, audio applications, machine control systems, test equipment and electronic device control. The contact is made from brass and is equipped with gold plating, which ensures good signal transmission. The connector also has a locking mechanism, which ensures that it stays securely in place even when subjected to shock and vibration.
