Working Principle of the 521139-1 Connector

The 521139-1 connector is a type of rectangular connector that uses the contact-rollover principle. This means that the male connector has a fixed contact that makes contact with the female connector by rolling over the female contact when the male connector is inserted. This rolling action allows for a durable connection with a high level of protection against short circuits, vibration, and other threats.

The male and female connectors are made of aluminum and have a molded black plastic seal at the base, which is designed to provide additional protection against shocks and vibration. The contacts are also made from gold-plated contacts designed for corrosion resistance and better performance. Therefore, these connectors are highly durable and can handle the toughest environments.

The 521139-1 connector is also designed to have a self-cleaning mechanism. When the male and female connectors are mated, the contacts roll over each other to clean any dust particles or other debris that may be present in the connection. This helps ensure a reliable connection and prevents any unnecessary problems.

Conclusion

The 521139-1 connector is a popular type of rectangular connector used in many industries. It is designed to offer highly reliable connections in various applications, including automotive, aviation, marine, medical, and power applications. Furthermore, this connector uses the contact-rollover principle for mating and has a self-cleaning mechanism that helps ensure reliable connections.
