643416-1 Application Field and Working Principle

643416-1 is a rectangular connected header and receptacle set designed for high-current applications. The connector is composed of two interlocking parts that fit together securely; the header and receptacle. The 643416-1 is commonly used in a variety of applications such as automotive, medical, and renewable energy.The application of the 643416-1 header and receptacle sets range from simple control of electronic devices to connections that required greater power. In most applications, it is used to join two circuits or devices together and provide a secure physical and electrical connection. The 643416-1 is an ideal choice for power connections in that the connection provides secure, stranded contacts that are highly reliable at higher currents.The 643416-1 headers and receptacles are made of zinc die-cast and feature keyed housings, preventing incorrect alignments. The connector’s housing is surrounded by a rubber gasket that helps protect the contacts from moisture and corrosive elements, making the connector able to withstand harsh environmental conditions and ensure a good connection at the same time. The insert position assurance (IPA) feature on the connector ensures proper alignment and locking of the two halves of the connector.The 643416-1 header and receptacle are both designed to receive female sockets, allowing the connection of other connectors or crimped wires with a variety of designs and insulation materials. The header is designed to hold and secure the female socket in place, while the receptacle is designed to securely lock the socket onto the header. The combination of the header and receptacle ensures a solid and secure connection that can withstand higher levels of current.The 643416-1 header and receptacle provide reliable and secure connections at higher currents. The connector’s features, such as keyed housings, insert position assurance, and waterproof enclosure, all contribute to making the connector suitable for high-current applications. The connector is an ideal choice for applications that require reliable and secure connections with higher current.
