D-Sub Connectors, DALC-J15SAF-23L9E Application Field and Working Principle

Introduction

Male and female D-Sub connectors are among the most popular connection components used in application fields, such as industrial control panels, machinery, electronic, and telecom sysrms.The DALC-J15SAF-23L9E is one type of D-Sub connector, mainly used in applications requiring a low-level signal interface. In such applications, a low-level signal (such as a digital logic signal) is typically transferred from one connector to another.

Application Field

The DALC-J15SAF-23L9E D-Sub connector’s application field mainly includes industrial control systems, motorized automobiles and autocontrol electronics, communications terminals, etc. In specific usage, it can be used in on-vehicle computer systems, data transmission terminals, data acquisition systems, data processing systems, data processing centers, etc. This type of D-Sub connector generally employs an EMI shielding shell, which provides excellent isolation and electrical insulation from nearby electronic and electrostatic interference. This shields the internal components from such interference, thus sends cleaner and more reliable signals to the connected device.

Structure and Working Principle

The structure of the DALC-J15SAF-23L9E D-Sub connector is composed of a series of high-precision metallic parts. It contains multiple pins arranged in two rows, which face each other in the D-shaped opening of the connector body. This connector includes shielded contact finger springs with connectors which form the signal and power connection. When the two D-Sub connectors mate, electrical contacts between the pins and the contact finger springs establish a reliable electrical connection for data and power exchange.

Conclusion

In conclusion, the DALC-J15SAF-23L9E D-Sub connector is a reliable and efficient connection component for low-level signal applications. It is widely used in industrial control, electronic, and communication systems. Its EMI shielded shell efficiently protects the signals from interference, and its metal parts provide reliability and stability during signal exchange between the two connectors.
