Introduction to the DBMM21W1SZ D-Sub Connector

The DBMM21W1SZ is part of the D-Sub Connector family of products manufactured by Amphenol. It is a 21-way connector that is designed to provide reliable, low-cost interconnects for a variety of electrical and electronic circuits. The connector has been designed to suit a variety of applications ranging from the automotive industry to telecommunications and other industrial areas.

Overview of the DBMM21W1SZ Connector Design

The DBMM21W1SZ is a two-piece connector that consists of a male and female component. The male connector consists of a receptacle fitted with 21 pins that lock into corresponding drill-holes on the female part of the connector. This ensures a secure connection that can withstand external shocks and vibrations. The body of the connector is made from a durable thermoplastic material making it resistant to corrosion from environmental elements such as salt water, oil, and fuel. The receptacle also features a rubberized seal which further protects the connector from outside contaminants. This single-piece connection results in an efficient, lightweight, and compact design which reduces the size and weight of the final product.

Application and Working Principle of the DBMM21W1SZ Connector

The DBMM21W1SZ is designed to be used in a variety of automotive, telecommunications, and industrial applications. In automotive applications, the connector is used to provide a reliable electrical connection between the various components of a vehicle. For example, it can be used to connect the starter relay, the fuel pump, and the electronic fuel injection systems. In the telecommunications industry, the connector is used to connect telephone lines. To protect the connections, a shielding gasket is placed between the male and female components of the connector, which provides excellent resistance to electromagnetic interference. Industrial applications include connection to robot arms, conveyors, and other industrial machinery.The DBMM21W1SZ connector works by providing a mechanical connection between two components/devices. The male component of the connector has 21 pins that protrude into corresponding holes on the female component of the connector. This ensures a secure connection that can withstand high temperatures, mechanical shock and vibration. In addition, a shielding gasket is used to further protect the connection and prevent interference from electromagnetic sources.

Conclusion

The DBMM21W1SZ is a reliable and robust two-piece connector that is designed to be used in a variety of automotive, telecommunications, and industrial applications. It is designed to provide a secure mechanical connection between two components and offers excellent resistance to electromagnetic interference. The lightweight and compact design of the connector also makes it suitable for applications where space and weight are a concern.
