Rectangular Connectors, also known as headers, male pins, are widely used devices for linking multiple circuits in electronics. The 280389-2 is no exception and is an electrically haevy-duty, high-reliability device. This article will explain the application field and working principle of the 280389-2.

The 280389-2 rectangular connector is primarily used in Aerospace, Military, and Industrial grade applications. Owing to its robust design, the connector can withstand environmental and electromagnetic forces, making it a perfect choice for high reliability applications. It is also widely used in data communication and wireless solutions, avionics, radar and defense systems, audio-video equipment, broadcasting systems, wireless networks, and other critical applications.

Specific features of the 280389-2 rectangular connector include a maximum temperature of 205°C for the plated contacts, high current capability of up to 25 amps, a maximum voltage rating of 600 Vac, and a lifetime of 5 to 10 million cycles. The connector also supports custom specifications such as anti-surge, high noise immunity, radiation resistance, and other special functions.

The 280389-2 rectangular connector is constructed using a metal shell, a thermoplastic insulator, and spring-loaded male pins. The shell is designed to protect the electrical connection, prevent mechanical shock, and provide mechanical strength for wire-to-wire connections. The thermoplastic insulator is used to protect the electrical currents and also helps to reduce radio frequency interference. Finally, the spring-loaded male pins provide electrical contact by providing a secure and reliable connection between the two components.

The 280389-2 rectangular connector is usually offered in a fully-sealed version with brass or steel shells. This is usually preferred for high-humidity environments. Additionally, the connector is available in a semi-sealed version, which is suitable for applications where environmental protection is not a primary consideration. In both versions, the connector utilizes a combination of male and female pins. The male pins are typically made of brass while the female pins are made of stainless steel.

The 280389-2 rectangular connector also has a variety of options for its electrical characteristics. These include different contact diameters, contact gold plating, contact crimping, retention force values, and contact areas. Contact gold plating is used to provide a corrosion-resistant contact surface while contact crimping ensures a secure connection between the connector and the mating component.

In addition, the contact force of the connector can be adjusted using a special tool. This ensures that the connector is properly secured when in use and enables its easy removal after use. Finally, the contact area of the connector can be configured for a variety of applications. For example, the contact area can be configured for signal, power, or mixed-signal use.

In conclusion, the 280389-2 rectangular connector is a high-reliability, versatile, and robust device which is suitable for a variety of Aerospace, Military, and Industrial grade applications. It is constructed using a metal shell, a thermoplastic insulator, and spring-loaded male pins and offers customizable electrical characteristics such as contact gold plating, contact force adjusting, and contact area configurations. Additionally, the connector can be offered in fully-sealed and semi-sealed versions and is capable of withstanding extreme temperatures and environmental conditions, making it an ideal choice for high-reliability applications.
