D-Sub Connectors

D-Sub connectors, such as 205556-2, are very common in use and offer a wide variety of features and specifications for users to find. This article will discuss the application field and working principles of the 205556-2 connector.

Application Field and Benefits

D-Sub connectors are applied in many different areas, including computers, consumer electronics, communications, medical, industrial, and automotive. The 205556-2 type specifically is particularly agile and multi-functional, so it is commonly used in general industrial installations and automation systems.

The 205556-2 connector is a compact and lightweight, yet sturdy connector that offers many design advantages over traditional connectors. Due to its small size, it can be easily integrated into many types of industrial systems. It also has a more stable and robust performance for long-term operations. It features secure locking mechanisms that ensure reliable mating between the plug and the receptacles. It is rated for up to 32A and 300V, making it suitable for harsh and industrial environments.

Working Principle

The 205556-2 connector is designed with two types of control contacts, the male and female contacts. The male contacts consist of two U-shaped pins that slide into the female receptacle when the connector is mated. The female contacts are located on the back of the male side of the connector and consist of four evenly spaced metal pins. When the connector is mated, the male contacts enter the female contacts and make electrical contact. These contacts are secured with a locking mechanism, preventing movement that could cause poor electrical contact.

In addition to the contact pins, the connector also incorporates an indicator contact. This contact is located in the center of the connector and is used to indicate the status of the mating operation. When the connector is properly mated, the indicator contact is closed and an LED located on the connector body will illuminate. If the connector is not properly mated, the indicator contact is open and no LED illumination will be visible.

The connector also incorporates a seal for dust protection. The seal is located in the center of the connector and helps to prevent the ingestion of dust and other foreign objects. The seal is also designed to provide a watertight connection when the connector is mated.

Conclusion

The 205556-2 D-Sub connector is a compact and robust connector that offers many design advantages over traditional connectors. It is suitable for a wide range of applications, including industrial installations and automation systems. The connector features secure locking mechanisms to ensure a reliable connection and also includes dust protection with an integrated seal. Its small size and performance make it an ideal choice for commonly used connectors in many industries.
