Rectangular Connectors - Headers, Male Pins

The 20021611-00030T4LF is a standard rectangular connector, also referred to as a header or male pin. These types of connectors are widely used in both commercial and industrial applications, largely due to their simple yet versatile design. They can be used to carry electrical signals or serve as a physical connector between two different components.

History

Rectangular connectors have been used in the electronics industry since the early 20th century. They were initially used for telephone and telegraph systems, but were later adapted for use in a variety of other applications such as radios and televisions. Today they are used in a wide array of electronics, from audio and video equipment to computers and home automation.

Design

Rectangular connectors consist of two primary components; the "header" and the "male pin". The header is the portion of the connector that actually makes contact when connected. It is typically a metal stamping, and is either made from brass or stainless steel. The male pin is the portion of the connector that is inserted into the mating part, and is typically made from brass. Both components are gold plated for improved durability and corrosion resistance.

Applications

Rectangular connectors are commonly used in a wide range of applications. One of the primary uses of the type of connector is in the production of Printed Circuit Boards (PCBs). These connectors are typically soldtered onto the board to provide a secure connection between components and the board itself. They are also used to interconnect components, such as capacitors, transistors and resistors. Other common uses include the connection of wires within enclosures, and the connection of wires or cables within electrical and electronic equipment.

Working Principle

Rectangular connectors are designed to allow for a reliable and secure connection between components. When a header is connected to a male pin, the metal surfaces of each contact each other, providing the connection. This connection is achieved through a process known as "pinning". In this process, the metal contacts are made sufficiently tight that they cannot be separated unless the connector is disengaged. This tight connection ensures that the electrical signals carried through the connector remain safe and uninterrupted.

Advantages

The primary advantage of rectangular connectors is their versatility. They can be used in a variety of applications and are capable of carrying both digital and electronic signals. Additionally, they are economical, easy to install, and have a long lifespan. Furthermore, they offer excellent electrical insulation, making them ideal for use in hazardous environments. Lastly, they are capable of withstanding high temperatures, making them suitable for use in extreme temperature environments.

Disadvantages

The primary disadvantage of rectangular connectors is that they are not as reliable as other types of connectors. Additionally, the connections they form can be prone to oxidation, which can result in weak signals or complete loss of connection. Finally, because of their design, they have limited compatibility with certain components, making them less suitable for use in certain applications.

Conclusion

Rectangular connectors are an extremely versatile type of connector that can be used in a variety of applications. They offer excellent electrical insulation, high temperature performance, and are economical and easy to install. However, they are not as reliable as other types of connectors, and can be prone to oxidation, limiting their usefulness in certain applications. As such, they should be reserved for applications where other more reliable connectors are not available.
