Working Principle

The 65780-051LF is a two-part system consisting of a modular header and a socket. The header and socket both have a varying number of pins, depending on the variant chosen. The header has a metal shell and contact pins, while the socket has a thermoplastic insulator, metal shell and flexible metal contacts.

When joining the two components of the connector, the pins on the header are inserted to the flexible contacts of the socket. As the header is inserted further, the flexible contacts are forced open, creating a secure, vibration-proof connection. The metal shell of both components lock the two components together, ensuring a good electrical connection and completing the connection.

Conclusion

The TE Connectivity 65780-051LF is a high-performance rectangular connector used in many industrial as well as consumer applications. It is a two-part system consisting of a modular header and a socket, which when connected provide secure and vibration-proof connections. Its excellent design ensures increased reliability, with low contact resistance and a metal shell for a good electrical connection.
