Rectangular Connectors - Headers, Male Pins

The 2-644749-2 rectangular connectors are a very common type of electrical connectors, used in a variety of settings. They consist of two parts, the header and the pin, which mate together to form a connection. The header is a block with a number of metal pins protruding from one end, while the pin is usually a single piece of metal with a plastic or metal outer casing. The header and the pin connect with each other via slots or small grooves, thus forming a secure electrical connection.

Application Field

The 2-644749-2 rectangular connectors are primarily used to connect electrical components such as sensors, actuators, and motors to printed circuits. This type of connection is often used in industrial applications, where the environment may include strong vibration and harsh conditions. Additionally, they are suitable for use in low-voltage applications such as laptop power supplies, so they are often used in consumer electronics.

Working Principle

The working principle of 2-644749-2 rectangular connectors is very simple. When the header and pin are mated together, the metal contact points within the header and pin connect. This creates an electrical circuit that allows current to flow between the components connected to each end. Since the pins of the header have a smaller diameter than the rest of the body, which ensures a secure fit and low electrical resistance when mated.

Advantages

The 2-644749-2 rectangular connectors offer a number of advantages over other types of connectors. First, they are relatively inexpensive and easy to manufacture. Second, they have a low contact resistance due to the small diameter of the contacts. Third, they provide a secure and reliable connection even when exposed to harsh conditions. Finally, the two parts are easy to disconnect and reconnect, making them suitable for a variety of electrical applications.

Conclusion

The 2-644749-2 rectangular connectors are a valuable and versatile electrical component. They are cheap, easy to manufacture, and provide a low contact resistance. They are suited for a variety of applications, both industrial and consumer, and are capable of withstanding harsh conditions. All in all, they are an effective and reliable way to create electrical connections.
