Introduction

D-Sub connectors are one of the most common types of electronic connectors. They are designed to be used in a variety of applications and come in a range of sizes and shapes, the most common of which is the DBMR21W1S. This type of connector is used in data transfers, multimedia displays, serial communication, and power supplies.

Application Field

The DBMR21W1S is used primarily in computer equipment, and is a two-position male connector. It has 21 pins, and it is commonly used for video, audio, and communication connections. It is also used in other interfaces, such as parallel ports for printers, as well as RS-232 cables, and for networking between computers.The DBMR21W1S connector is typically used in high-speed data communication applications and advances the signal transmission rate of data. As it is a shallow connector, it reduces the overall size of the connected device. Additionally, it is widely used as a power source connector due to its low contact resistance and insulation capabilities.

Working Principle

In terms of working principle, the DBMR21W1S connector is designed with an advanced contact system that enables high-speed signal transmission. It has an internal contact system which slides into the plastic housing and makes a physical connection with the metal crimp contacts. Depending on the type of connection, such as using a power or data connection, the connector has been designed to accommodate different types of contact resistance and insulation solutions to ensure an adequate connection.When using the DBMR21W1S, it is important to ensure that the contacts are closed with enough force to create a secure connection. It is also important to note that the connector must not be mishandled as it can cause the contacts to become loose and malfunction.

Conclusion

The DBMR21W1S is a versatile and common type of connector that is used in a variety of applications. It is designed to enable high-speed signal transmission and is used mainly as a power source or data transfer connector. To ensure an adequate connection, its internal contact system must be properly handled and maintained. With proper use and maintenance, the DBMR21W1S can provide a secure and reliable connection.
