Rectangular connectors, such as 44432-0401-style headers, male pins, and 2.00mm centerline, are used to provide reliable electrical contacts when two circuit boards must be connected. As you look at the connector\'s specifications such as maximum rated current and temperature, it is important to understand both the application field for which they are used and the underlying principle that allows them to do their job.

Application Field

44432-0401-style connectors are typically used in the communications, office equipment, automotive, industrial, and consumer electronics markets. These types of connectors are suitable for making connections between medium pin counts of 10-50 pins. The key benefit of using this type of connector is that they generally provide a reliable and secure connection. This makes them ideal for applications such as making secure connections between a printed circuit board (PCB) and a power supply, providing power-in and power-out connection points with the use of an adapter, and making connections between multiple circuit boards in a single system.

In addition, these connectors are often used where there is no room for error due to the fast data transfer rates of the communications or industrial equipment. The 44432-0401-style connectors are also designed with durability in mind, which makes them ideal for long-term corporate and industrial applications.

Working Principle

Connectors of this type utilize metal pins inside an insulating base. The base contains a series of holes for the pins to fit into and lock securely. One side of the connector has a male pin which is inserted into the other side of the connector, and the pins are then locked into place by the force of the metal pins as they press against each other. This ensures that when the connector is actively engaged, it will provide a reliable and secure connection.

In order to ensure the security of the connection and the quality of the signal, the pins must be precisely spaced and aligned. The metal pins are manufactured to ultra-tight tolerances so that the holes in the base are aligned with pins in the connector, allowing for a perfect connection.

Once the connector is engaged, it seals the connection from dirt, dust, and other contaminants. The connector’s durability is further enhanced by its effective EMI shielding capabilities. The shield protects signals from interference caused by external electromagnetic fields.

Conclusion

44432-0401-style connectors are popular for industrial, commercial, and consumer electronic applications because of their reliable connection, tight tolerances, and EMI shielding capabilities. They are designed to provide a secure connection over the long-term, allowing for unfettered data transfer without interruption. The metal pins in these connectors are designed to lock securely into the insulating base, allowing for a secure and seamless connection between two separate PCB’s.
