DBM21W1SR Connectors, Interconnects

The DBM21W1SR is an example of a D-Sub connector. A D-Sub connector is type of electrical connector, which features a design consisting of a metal shell with multiple parallel rows of electrical pins inside. The DBM21W1SR is commonly used with networking and data connections. It is often found in high-speed communication and data storage applications, where high performance and reliability are required.

The DBM21W1SR is an example of a small form factor D-Sub connector utilizing the Mini DIN-7 pin configuration. It features a 9mm shell size with a 25-pin connector type. The design of this type of connector ensures a secure and reliable connection, as it is designed to fit two mating pieces together tightly and securely. It also provides a contact resistance of less than 0.5 ohm, ensuring an optimal electrical connection.

To understand the working principle of the DBM21W1SR, it is important to first understand the materials and construction used in its make up. The DBM21W1SR is composed of a zinc die-cast shell, 9mm coupler, EPDM seal, stainless steel contact pins, stainless steel insulated ground plate, and an ABS UL 94 V-2 rated plastic housing. All these components work together to form a secure and robust connection.

The zinc diecast shell is made from zinc alloy and is designed to be extremely hard, with high corrosion resistance. This helps protect the connectors from wear and tear, as well as environmental damage. It also provides mechanical stability and serves as a secure and reliable way of joining two pieces together. The 9mm coupler adds an additional level of sealing, providing a strain relief for the connector.

The stainless steel contact pins inside the DBM21W1SR are made to be both rugged and highly conductive. This ensures a low contact resistance, which is crucial for reliable and error-free connections. The contacts are also UL listed and rated up to 12A/250V, ensuring optimal current-carrying capacity.

Finally, the stainless steel insulated ground plate serves as a ground connection, providing extra protection against electrical interference and providing an efficient current path. The ABS UL 94 V-2 rated plastic housing is used to encase the entire connector and protect it from external damage.

In conclusion, the DBM21W1SR is a small form factor D-Sub connector capable of providing reliable and secure data connectivity. It is designed to be resistant to both physical and environmental damage, featuring a zinc die-cast shell, 9mm coupler, EPDM seal, stainless steel contact pins, stainless steel insulated ground plate, and an ABS UL 94 V-2 rated plastic housing. This ensures a low contact resistance, which provides an optimal electrical connection, as well as optimal current-carrying capacity. The DBM21W1SR is often found in high-speed communication and data storage applications, where high performance and reliability are required.
