D-Sub Connectors

The DCM-21WA4P-K87 is a type of D-subminiature connectors, or D-sub connectors. Similar to other kinds of connectors, D-subs are diverse in application fields, shape and size. As a result, the DCM-21WA4P-K87 has its own corresponding application fields and working principles. In this article, those two points are going to be the centre of attention.

DCM-21WA4P-K87 Application Fields

DCM-21WA4P-K87 is a D-sub connector consisting of 4pin female connector with a flat contact surface and 4pin male steel pins sticking out from the back. This type of connector is named Class IP65, which means it is dust tight with a tight contact for users that need a waterproof option. In other words, it is suitable for both dry and wet environments with temperature levels ranging from -40°C to +105°C. Therefore, DCM-21WA4P-K87 is commonly used in industrial and commercial settings particularly for specific applications such as automated equipment, electrical control systems, and automobiles. The elongated shape is ideal for applications where the connection needs to be secure but can be detached quickly.

DCM-21WA4P-K87 Working Principles

The working principle by which the DCM-21WA4P-K87 functions is similar to that of most other D-sub connectors. It features both female and male components which consist of contacts with spring-loaded mechanisms for a secure connection each time. The female component is typcially packed in a high-impact nylon housing which acts as a dust and heat resistant barrier. This ensures users have an airtight seal while maintaining connection quality. The male component is usually made from zinc-plated iron pins which are inserted into their corresponding housing. These pins generally stick out from the back of the D-sub and are secured through a retention device. This creates an additional layer of protection against dust and dirt.

The connection between the two components is made through metal-to-metal contact. This contact enables the necessary energy transfer for electricity to flow between the two components. Moreover, this contact has a v-shaped design which enables it to conform to the pins and provide additional congruency. This is important for providing users with stability and strength to withstand any jerking or vibration that may take place. In other words, the contact areas are able to keep the connection stable despite being exposed to external interference.

Conclusion

The DCM-21WA4P-K87 is a dust tight Class IP65 connector that is perfect for users that need a waterproof option. It is most commonly used for applications like automated equipment and vehicles that might experience vibration or jerking. This is because the contact areas feature a v-shaped design which gives additional congruency for stability and maintains a secure connection. Overall, the DCM-21WA4P-K87 has a wide application field and makes use of metal-to-metal contact for energy to pass between the two components.
