Rectangular Connectors - Headers, Male Pins are a type of electrical connector used to transmit energy, signals, and data between two devices. They come in various sizes and shapes, and are typically designed for a specific purpose such as data transmission, connecting a variety of cables and wires, or providing a secure and waterproof connection. The most common types of rectangular connectors are the header, male pin, and right angle connector. While each type has its own unique application field and working principle, a general understanding of all three will help determine which is the best option for a given application.

Headers are the most versatile rectangular connector, and are available in a variety of forms. A header is typically composed of a single pocket or discrete pin, and the entire connector is mounted on a standard PCB. Headers can be used to connect a single set of wires, or multiple wire sets, depending on the design. The most common application fields for headers include computer peripherals, telecom device interconnections, and board-to-board connections.

Male pins are a type of rectangular connector specifically designed for applications that require a secure and durable connection between two components. These connectors typically feature a number of pins, which are mounted on the device end, and then inserted into the mating housing. When in use, the male pins will provide a secure connection from the device to the mating housing. Some of the common applications of male pins include power supplies, audio and video devices, and electronic devices.

Right angle connectors are slightly different than the traditional connector, and are used to create an angle between two components that can then be connected by a cable. These connectors are especially useful when space is limited, and can be used to form a connection path where otherwise one might not be available. Right angle connectors are often found in applications such as computers, audio/video, and automotive electronics.

In conclusion, rectangular connectors - headers, male pins, and right angle connectors, each have their own unique application fields and working principles. While some are better suited for certain applications than others, understanding the features and benefits of each type will help to make sure that the correct connector is chosen for the job at hand.
