Rectangular Connectors in the form of Headers, Male Pins, (3-644992-6) are a type of mechanical connector made of metal or plastic and are used to connect two or more lines or circuits. Generally, pins transmit electrical signals and headers are receptacles that are placed on mounted devices such as circuit boards.

Application Field

Headers, Male pins have a wide range of applications. They are often used in both analog and digital circuit boards. In particular, they provide a connection to circuits and systems that require precision and reliability. 3-644992-6 Headers, Male Pins are commonly used in the automotive, aerospace, and industrial sectors, as well as in the electronic appliances.

Working Principle

The 3-644992-6 includes a metal or plastic header pin with a built-in spring. The spring ensures that the connection is made and remains secure. The header pin is inserted in a PCB thereby making contact with the PCB\'s conductive surface under the contact point. When the header pin is removed from the circuit board, the spring ensures that the oil collected during the contact process, such as flux or other contaminants, is pushed out from the spring, thus maintaining a reliable electrical connection.

The oil collected by the spring will create an insulating layer between the contact pins and the PCB, which can cause electrical resistance if the contact pins are not periodically cleaned. To prevent this, the 3-644992-6 header pin can be designed with a special wiping action that removes these contaminants during the insertion and removal process, leaving the contact pins properly cleaned after each use.
