Introduction

The DDMA-78S (double deformed male array) connector is a widely used type of D-sub connector. Like all D-Sub connectors, DDMA-78S is a type of electrical connector with multiple pins that can be used in a wide variety of applications from computers and telecommunications to audio-visual systems. While there are many different types of D-sub connectors, each with different features and designs, the DDMA-78S has a unique design and application. In this article, we will look at the application field and working principle of DDMA-78S connectors.

Application Field of DDMA-78S

DDMA-78S connectors are typically used in a range of computer and telecommunications applications. This includes commercial server systems, mission critical communications systems, and other applications requiring high-speed data transmission. In addition to this, the DDMA-78S is often used in industrial automation systems due to its ability to handle a variety of signals and power requirements. The DDMA-78S is also commonly used in audio-visual systems as it has very low signal loss when compared to other types of connectors.

Working Principle of DDMA-78S

The DDMA-78S connector is designed with two rows of pins that are arranged in a deformed male array. This array of pins is designed to provide a more secure connection as each pin is slightly bent in order to increase friction and prevent potential disconnection. Additionally, the pins are arranged in a way so that contact is made over the full length of each pin. This helps to ensure that there is no signal loss and that the connection remains secure.The DDMA-78S connectors also have an array of shielding features to help protect against any electromagnetic interference. This includes high grade shielding material to the contact pins, as well as full contact shielding to the entire body of the connector. The DDMA-78S connector is also designed to be able to operate in a wide range of temperatures and is rated for use in temperatures from -55°C to 85°C.

Conclusion

The DDMA-78S connector is a widely used type of D-Sub connector. It is typically used in a range of computer and telecommunications applications, as well as in industrial automation and audio-visual systems. The DDMA-78S connector has a unique design that features two rows of slightly bent pins to ensure a secure connection. It also has an array of shielding features to help protect against any electromagnetic interference.
