Rectangular Connectors - Headers, Male Pins

Rectangular connectors are one of the most commonly used types of electrical connectors. They are designed for many different applications including the connection of wires, power supplies, and other components. These connectors can be divided into two main categories; headers and male pins.

Headers

Headers are a type of rectangular connector that includes a plastic housing and two metal posts. These posts are usually fitted with small screws that allow them to connect to each other, forming an electrical connection. The posts may also be fitted with prongs that make it easier to attach wires or other components. Headers are typically used for applications such as circuit boards, testing equipment, and communication links.

Male Pins

Male pins are a type of rectangular connector that includes a metal post. Unlike headers, these posts do not include screws and must be soldered to the board or other component. Male pins are typically used for applications such as systems that require a more reliable, steadier connection. Examples of common male pin connectors include BNC connectors, RJ-45 connectors, and D-sub connectors.

Application Field and Working Principle

Rectangular connectors have a wide variety of applications, ranging from consumer electronics and industrial automation to medical and military applications. They are used to connect wires, power supplies, and other components in a safe and reliable manner. The posts on headers and male pins both allow for a secure electrical connection to be established. Headers have the added advantage of having screws that make them easier to attach and detach. Rectangular connectors are a reliable and reliable option for many applications. They are designed to withstand a wide range of temperatures and environmental conditions, making them well-suited for outdoor applications. They also have the added benefit of being easy to install and maintain. With the wide range of sizes available, these connectors are an ideal choice for many different applications.
