79257-404HLF

Rectangular Connectors - Headers, Male Pins

The 79257-404HLF rectangular connector, also known as header connectors and male pins, is a type of electrical connector widely used for a variety of applications. It is the most popular type of connector due to its versatile design and wide range of sizes. It is available in both single and dual rows, and can be used in applications ranging from commercial to military.

Construction

The 79257-404HLF rectangular connector is a two-piece connector consisting of a male plug and a female receptacle. The plug is composed of a molded housing with four prongs (poles) extending from it. The prongs are made of brass and are gold-plated for better conductivity. The receptacle has two opposing mounting holes to allow the user to attach the connector to the mounting surface. The housing of the receptacle also contains four channels which mate with the prongs of the plug.The 79257-404HLF is designed to be used with electrical systems containing standard 0.050 or 0.100 pitch connectors. The connector comes in a variety of sizes, including 1x2, 2x2, 3x2, 4x2 and 5x2. The width of the connector is 0.412 inches and the height is 0.312 inches.

Application Field

The 79257-404HLF connector is ideally suited for use in telecommunications, consumer electronics, automotive, and other electrical applications. Its small size, ease of use, and wide range of sizes make it an ideal connector choice for many applications. It is commonly used to connect audio and video cables, power cords, and other low-voltage cables. It is also commonly used in PC boards, home theater systems, and other audio-visual equipment.

Working Principle

The 79257-404HLF connector works by allowing electrical current to flow between two devices. The plug portion of the connector contains four prongs, which mate with the four channels in the receptacle portion of the connector. When the two halves of the connector are joined, the prongs touch and create a secure connection which allows the current to flow. The materials used for the prongs are highly conductive, so the amount of electrical resistance is kept to a minimum.

Advantages

The main advantage of the 79257-404HLF connector is its versatility. Due to its small size and wide range of sizes, it can be used for many different applications. It is also affordable and easy to use, which makes it an attractive option for many users. Additionally, the gold-plated prongs ensure a secure and low-resistance connection, making it suitable for use in high-performing applications.

Disadvantages

The primary disadvantage of the 79257-404HLF connector is its limited ability to carry large amounts of current. Due to its small size, it can only safely handle up to about three amperes of current. Additionally, the gold-plated prongs may corrode over time, causing the connection to become less reliable. As such, the 79257-404HLF is often unsuitable for use in high-powered applications or for applications in which the connector may be exposed to harsh conditions.

Conclusion

The 79257-404HLF rectangular connector is a versatile and popular type of electrical connector which is suitable for a wide variety of applications. Due to its small size, ease of use, and affordability, it is often the preferred choice for connecting audio and video cables, power cords, and other low-voltage cables. However, it is not suitable for use in high-powered applications or in harsh conditions due to its limited carrying capacity and potential to corrode.
