Working Principle

Amphenol 71991-420LF rectangular connectors consist of two matched parts: a socket part and a header part. The socket part is a female connector that is inserted into the header part. The two parts are firmly held in place by an integrated collar. The contact pins or sockets on the socket part allow the transmission of signal or power. The header part is attached to a device that requires an electrical connection. When the two parts are connected, the contacts first make contact and a permanent connection is established due to the mechanical stability of the collar. Contacts are further secured through the spring action of the connection, which additionally provides high vibration resistance and shockproofing. Amphenol 71991-420LF cylindrical connectors are designed with a locking mechanism that prevents unintentional disassembly of the connector. To unlock the latch, the user must manually disengage the latch. This feature helps to protect the electrical integrity of the connection and prevents accidental disconnection.
