Rectangular Connectors - Headers, Male Pins are designed for use in a wide variety of applications and making the proper electrical connection to the electronic component of the application. The 68491-402HLF Connector is a particular model produced by Molex, designed specifically for use as a power connector in high-density, low-profile, high-current applications.

Overview of 68491-402HLF

The 68491-402HLF Connector is a power header designed to accommodate two major types of rectangular connector contact systems. The system includes a complete, two-piece revolutionized header with its male pin receptacle. The individual parts of the header are designed to fit to ribbon cables as well as discrete wire cables. Molex refers to this particular modeled power header as a “mezzanine” power header because of its ability to switch between multiple power sources.

Construction of 68491-402HLF

The 68491-402HLF Connector is built with a combination of materials. The pin contacts and female receptacle pins are made from solid copper and are plated in gold or nickel. The header frame is constructed of black glass-filled thermoplastic which is UV rated. The header has two primary pieces, the chassis and pin receptacle, which are both made with integrated strain relief capabilities. The design allows the user to easily retract and reposition the contact pins within the pin receptacle.

Features of 68491-402HLF

The 68491-402HLF Connector is designed to handle high-density, low-profile applications and is capable of transferring up to 6 amps of power from one source to another. It has a maximum pin insertion depth of 2.14 inches and a pin diameter of 0.039 inches. The connector is designed to fit into a standard 0.097 inch diameter header connector slot, making it compatible with a wide range of applications. The connector is also rated to operate in temperatures from −25°C to +85°C, making it suitable for industrial and consumer grade applications.

Application Field

The 68491-402HLF Connector is designed primarily for high-density, low-profile, high-current applications such as power tools, medical equipment, computers, and consumer electronics. The power header can also be used in smaller applications such as telecommunications, aerospace, and military applications. Additionally, the connector features protection against EMI and is capable of accommodating both ribbon and discrete wire cables.

Working Principle

The 68491-402HLF Connector is designed to make connections between two header contacts. When a power source is connected to the male pin receptacle, electrical current passes through the pins and is carried to the power source or destination. The power is then transferred from the power source and pin receptacle to the header contacts, where it travels to the other side of the connection. The entire process occurs simultaneously, making a quick and reliable connection.

Conclusion

The 68491-402HLF Connector is a designed specifically for high-density, low-profile applications and is capable of transferring up to 6 amps of power. It features a combination of materials constructed in a two-piece revolutionized header with an integrated strain relief as well as two major types of contact systems for ribbon and discrete wire cables. The connector is designed to operate in temperatures from −25°C to +85°C, making it suitable for a wide variety of industrial, consumer grade and military applications.
