Rectangular Connectors, commonly referred to as headers, male pins and female sockets, are a type of electrical connection component developed for higher power applications. The 3428-2302 is a type of rectangular connector manufactured and distributed by Molex. This type of connector features four columns of rectangular pins, each separated by a shorter space and with a length of 17.5mm. It offers excellent performance for applications requiring extreme heat tolerance, wear resistance, and superior mechanical strength. In addition, the use of stainless steel contact pins and silver nickel-plated pins improve mating durability and lessen the possibility of electrical arcing.

Application Field

The 3428-2302 rectangular connector is primarily used in a variety of electronic products such as cell phones, LCD screens, medical equipment, security/surveillance systems, communications and automotive electronics. With its high-speed transmission and radio frequency (RF) signal quality, it is an excellent choice for applications that require greater signal integrity. This type of connector is often used in industrial, electronic, and automotive applications, including automotive control modules, on/off switches, motors, charging systems, and many other electronics.

Working Principle

The working principle of the 3428-2302 rectangular connector is based on the concept of electrical connection between two conducting parts. Once the connector is plugged into the target device, the contact plates that form the connector slide into the female socket. This creates an electrical connection between the two connector parts, through which electrons can flow freely.

When the motherboard is connected to the pins in the rectangular connector, electrons will flow from the source (motherboard) to the target (rectangular connector) by passing through the conducting contact surfaces. The electrons will then move through the components in the connected device, thus allowing the device to work. Once the electrons have completed their journey, the circuit is closed and the connection is complete.

The 3428-2302 connector is designed for use in harsh or environmental conditions, such as high heat, moisture, and dust. The use of thin contact plates in the rectangular connector ensures that the connection is not too thick and thus doesn’t sacrifice the signal quality. Additionally, the right contact surface finishes ensure that the connection pins can tolerate high temperatures and mechanical wear. Consequently, the 3428-2302 connector can resist wear and tear and withstand vibration and shock.
