Rectangular Connectors - Headers, Male Pins - A1-40PA-2.54DS(71)

A1-40PA-2.54DS(71) is a type of rectangular connector widely used in various fields, both industrial and commercial. It is a header with male pins, which consists of multiple components such as a rigid plastic body, metal contact pins, insulating tape or covers, silicone grease, locking clips and strain reliefs.

Applications

A1-40PA-2.54DS(71) header connectors are suitable for applications in a wide range of industries. Common applications include industrial automation, telecom equipment, medical equipment and instrumentation, automotive and robotic systems. They can also be used in data and communication products, including networking equipment, printed circuit boards and modems.

Design Features

The design of A1-40PA-2.54DS(71) header connectors consists of several key parts. The plastic body, for example, is designed to ensure that the pins are held precisely in place, providing a robust connection. The metal contact pins are designed to provide a secure and reliable connection to other mating components. The strain relief and locking clips are designed to provide additional protection to the connection and ensure that it is protected from external vibrations. The plastic body is designed with an interior solder cup, which is filled with silicone grease before the connector is assembled. This prevents the contact pins from becoming corroded and guarantees a long-term, reliable connection.

Working Principle

A1-40PA-2.54DS(71) header connectors are designed to be inserted into a corresponding receptacle to provide a secure, reliable electrical connection. The contact pins of the header connector will make contact with the receptacle contact pins when the header is inserted, completing the electrical circuit.The contact pins are made of materials that are able to maintain a strong connection even during vibration or movement. The strain reliefs ensure that the contact pins are held securely without being damaged by vibrations.When the connector is removed, the silicone grease acts as a lubricant between the contact pins to ensure that the contact pins do not become corroded or seize up when the connector is pulled out.

Conclusion

A1-40PA-2.54DS(71) header connectors are designed to provide an efficient and reliable connection for a variety of industrial and commercial applications. The rigid plastic body, metal contact pins and insulating tape or covers are designed to provide a secure connection, while the silicone grease prevents corrosion and seizing of the pins. The strain reliefs and locking clips are designed to protect the contact pins from vibrations and securely hold the connector in place.
