Rectangular connectors are some of the most widely used connectors in electrical and electronic equipment. They are used in a wide variety of applications, from harsh environments such as aerospace to consumer products such as computer peripherals. The 645861-2 is a rectangular connector header, male pins, and is an important component in many applications. This article discusses the application field and working principle of the 644861-2.

Due to its small size, the 645861-2 is most often used for applications in electronic devices, such as cell phones, medical devices, and computers. It is popularly used in boards that require small, compact connectors that can be easily integrated into the printed circuit board. This connector is also utilized in harsh environment applications, such as for rugged military and aerospace applications.

The 645861-2 has two headers, male pins, with a pitch of 2mm. The header pins are "angled" so that the electrical contacts are not perpendicular to the mounting board, but instead are angled to make a better electrical connection. The pins are constructed of solid brass material with gold plating and the connector is made of tin-plated brass and housed in injection molded plastic. The plastic material used for these connectors meets UL94V-0 standards for flammability, temperature range, and contact resistance.

The working principle of the 645861-2 relies on a connection pressure between the mating header pins and the header socket contacts. As the two pins inserted into the socket contacts, an outward force is applied, forcing the socket contacts outward, creating a firm electrical connection. This insures that a steady, reliable voltage is applied to the connected components and that the electrical contact is secure.

In order to ensure the longevity of the connector, it is important to use the correct socket contacts and mount the connector properly. The socket contacts should be purchased from the same manufacturer as the connector, ensuring that they are designed to work with the 645861-2. The mounting of the connector should be done according to the instructions provided, which may include securing the connector to the board with screws or rivets or using an adhesive. The instructions should also specify the correct wire gauge for the application. By following the instructions and using the correct contacts and mounting methods, the 645861-2 will provide a long lasting, stable connection.

The 645861-2 rectangular connector header, male pins, is highly versatile and widely used in a variety of applications. Its small size, rugged construction, and reliable electrical connections make it a great choice for a variety of electronic and electrical devices. By utilizing the correct socket contacts and mounting methods, the 645861-2 connector can be a reliable component in a successful product.
