Circular Connectors - Contacts

Circular connectors are used in a variety of applications due to their versatility and ability to quickly provide a high quality connection. Contact technology plays a major role in making this possible. In this article, we\'ll take a look at the 2803-10-00 contact, a popular contact for circular connectors, and examine its application field and working principle.

Application Field

The 2803-10-00 contact is a spring loaded, solder cup terminable contact which provides a reliable yet flexible connection for a wide range of applications. It is used mainly in the military, aerospace, automotive, industrial and telecom sectors. This contact is especially suitable for applications where frequent or repeated mating/unmating is required due to its spring-loaded design. This allows it to make a secure connection even after thousands of repeat cycles. It is also used for low-voltage alternating current (AC) applications.

Mechanical Design

The 2803-10-00 contact is a rectangular cross section contact with a crimp barrel at one end and a solder cup at the other. It is constructed from a wear-resistant copper alloy with a gold flash or nickel plating. The contact has an internal spring which provides the required tension which is necessary for making a secure connection. The dimensions of the contact are 16.0mm in length and 3.0mm in width.

Working Principle

When the 2803-10-00 contact is mated to its circular connector, the internal spring is compressed, allowing the contact to be securely held in place. This ensures that the electrical connection is maintained and that the connection remains reliable. As the connection is made, the electrical signals are transferred between the two components along the connector, allowing communication between the two sides.

Conclusion

The 2803-10-00 contact is a versatile, reliable and widely used contact for a variety of applications. Its spring-loaded design allows it to be used in applications which require frequent or repeated mating/unmating cycles. It is also suitable for low-voltage AC usage. By understanding its application field and working principle, we can better select the right contact for our needs.
