D-Sub Connectors: DBMMV21X1PN Application Field and Working Principle

D-sub connectors are a common type of connector used in industrial, commercial, and consumer applications where durability and contact flexibility are important factors. The DBMMV21X1PN connector is a particular type of D-sub connector which is specifically designed for automation, motion-control, and robotics applications. Below, we will discuss the application field and working principle for this connector.

Application Field

The DBMMV21X1PN is designed for industrial and commercial applications, and is ideally suited for automation, motion-control, and robotics applications. It is designed to provide improved electrical contact while also ensuring reliable performance in hostile environments. Some of the features which make it well-suited for such applications include:

• Robust mechanical construction with secure latching
• High contact density
• Low insertion force contacts
• Low profile design
• High vibration and shock vibration resistance
• High temperature range

The DBMMV21X1PN connector is commonly used in applications such as factory automation, food processing, packaging machinery, and other industrial and commercial applications. It is also suitable for applications in the automotive industry, medical electronics, and many more.

Working Principle

The DBMMV21X1PN connector is made of both ferrous and non-ferrous metals. The ferrous components, such as the shell and contact pins, are typically made of nickel-plated steel or brass, depending on the specific application. The non-ferrous components, such as the contact sleeves and insulators, are typically made of PBT or POM plastics. This ensures a durable construction which can withstand high temperatures and many types of environmental stressors.

This connector features a crimp-and-clamp contact system, meaning that the contacts are held in place by a lateral strain on the contact pin which displaces the contact sleeve against the contact pin. This ensures reliable contact and prevents any potential contact fatigue under normal operating conditions. Additionally, the DBMMV21X1PN connector can be configured with either solder or crimp contacts, allowing for further flexibility in its usage.

The DBMMV21X1PN connector also has an integrated strain relief feature which helps to reduce any strain on the contact pins. This helps to ensure that the contacts remain reliable and secure, even in harsh environments. Additionally, the shell of the connector is designed with a beveled edge, which helps to ensure that the connector can be inserted with minimal force.

Conclusion

The DBMMV21X1PN is a well-designed and reliable D-sub connector which is designed for industrial and commercial applications. It is typically used for automation, motion-control, and robotics applications, and is well-suited for harsh environments. It features a crimp-and-clamp contact system, an integrated strain relief feature, and a beveled shell edge, all of which help to ensure reliable contact and performance.
