644740-2

Rectangular connectors are one of the most commonly used connectors in various electronic devices and products. They are made of various materials such as plastic, metal, or a combination of both. The 644740-2 connector is an example of a two-piece rectangular connector that is used for a wide range of complex applications. This article will discuss its application fields and working principle.

Application Field of 644740-2 Connectors

The 644740-2 connector is most commonly used in a variety of industrial applications, such as robotics, semiconductor manufacturing, telecommunications, medical equipment, and measurement systems. It is suitable for enclosed environment applications due to its strong construction. It also offers excellent protection from dust, abrasion, and moisture. In addition, its two-piece design offers more reliable connections than single-piece connectors.

Furthermore, the 644740-2 connector has a compact size and high-density pin arrangement that make it a preferred choice for many integrated circuits. It is the most commonly used connector in industrial automation systems, such as those used in the automotive, chemical, and medical industries.

Working Principle of 644740-2 Connectors

The 644740-2 connector is a two-piece design with a male and female side. The two halves are mated together using an array of contact points arranged in an H-shape pattern. The contacts are made of phosphor bronze and come with a variety of finish options, including gold, silver, or tin plating. The contact points are then secured with a pair of metal screws, and held in place with a plastic sealant.

The contact points are arranged in a specific pattern to ensure reliable electrical connections. This goal is accomplished by a combination of the physical arrangement of the contact points, as well as their electrical properties. The contact points are designed to create a tight fit between them, reducing the chances of electrical shorts and providing a secure connection.

Once the two halves of the connector are mated, a series of mechanical and electrical tests are then performed to ensure its durability and performance. This includes tests such as voltage drop, contact resistance, and insulation resistance. The 644740-2 connector is rated at an operating temperature range of -20° to 80°C, and a voltage rating of up to 300VAC.

The 644740-2 connector is an ideal choice for applications where reliability, robustness, and long-term performance are essential. Its two-piece design and high-density contact arrangement make it suitable for a variety of complex applications. It is also one of the most commonly used connectors in industrial automation systems, making it a popular choice for a wide range of applications.
