643140-3 is a rectangular electrical connector. It provides high reliability and a highly cost-effective connection solution for applications where protecting the power connection from dirt, dust, and debris is a priority. This connector can be used in a wide variety of applications.

This connector is typically used in the automotive, industrial, and consumer electronics markets. Its small size and compact design make it ideal for tight spaces, while its shielding helps to prevent EMI/RFI interference. Its robust and secure connection allows for reliable power connections in harsh environments.

Among its features, the 643140-3 connector includes a dual wall construction, which provides extra robustness and protection from dust and debris; a latch for secure mating; a separate ground terminal to help reduce EMI/RFI interference; and gold-plated terminals to improve with improved corrosion resistance over standard steel terminals.

In terms of its working principle, this rectangular electrical connector uses a male-pin terminal mounted on the connector. When the connector is connected to its mating connector, the male-pin terminal makes contact with the female-pin terminal of the mating connector to provide a robust and secure electrical connection.

The most common style of 643140-3 connector is the straight-through connector. It is constructed of metal or plastic with a single row of pins along each side. When the mating connector is inserted, the male-pin terminals make contact with the female-pin terminals of the mating connector, providing a secure, reliable electrical connection.

The 643140-3 connector is also offered in the reverse-through version, which contains a reversed row of pins on each side. When the mating connector is inserted, the female-pin terminals on the reverse side make contact with the male-pin terminals of the mating connector, providing a secure, reliable electrical connection.

The 643140-3 connector is also available in a combo version, which includes both the straight-through and reverse-through versions of the connector. This allows for greater flexibility in the design of the electrical system.

In conclusion, the 643140-3 is a highly reliable, cost-effective rectangular electrical connector used in a variety of applications. Its dual wall construction, latch for secure mating, separate ground terminal, and gold-plated terminals enhance the performance of this connector and help to ensure a robust, secure electrical connection. The 643140-3 connector is able to meet the needs of applications where protecting the power connection from dirt, dust, and debris is a priority.
