Rectangular Connectors - Headers, Male Pins

Rectangular connectors, sometimes referred to as headers, male pins, or pin headers, are specialized types of connectors that are commonly used in circuit board assemblies and various electronic components. This type of connector is typically composed of two main parts, one body and one mating part. The body is made up of a rectangular housing, which is the part that is installed onto the printed circuit board. The mating part is usually a set of pins that is connected to the electrical circuit. The pins are then inserted into the header and secured with a clip or lock. Rectangular connectors are designed for easy and reliable connection of electrical circuits in order to power and control components such as microprocessors, transistors, LED\'s, memory chips, and more.

Rectangular connectors vary in number pins, which range from 6 to 200 pins. The number of pins needed depends on the type of electrical components used and the circuit\'s complexity. It should be noted that the same type of header can have different length depending on its pin density. Pin density is the number of contacts per unit of length, and it is indicated in a number followed by a letter, which stands for its unit of measure. For example, 951220-8622-AR indicates a pin density of 20 pins with 2.54mm pitch.

Before purchasing a rectangular connector, one must determine what type of connector is right for the application. Connectors can vary in design from 0.5mm to 5mm in pitch, and the number of pins can range from 4 to 200. They are usually in right angle orientation and available with surface mount technology (SMT) or through-hole (DIP) mounting. Additionally, headers can vary in materials such as metal alloys, plastic body material, and various contact metals.

Rectangular connectors can be used in a wide range of electronic components and applications, such as power and signal transmission, lighting, automation, communication, automotive, surveillance, medical, and aerospace. The most common applications are for the interconnection of printed circuit boards or parts, the power connection of PCBs or components, and the patch panel connection of external communications lines.

The working principle of a rectangular connector is fairly straightforward. When the pins of the mating part are inserted into the header, an electrical connection is created which passes power and signals from one circuit board or component to another. Depending on the type of selector that is chosen, the power and signals that are transmitted can be either AC or DC. Additionally, the contacts of a rectanguler connector are usually spring-loaded and this allows for improved contact retention and secure mating. In order to ensure a reliable connection, it is important to buy the right material for the application.

Rectangular connectors with headers and male pins provide reliable connections between componets in order to transmit power and signals. However, it is important to carefully consider the number of pins, pitch, and material before purchasing a rectangular connector to ensure that it is best suited for the application. By taking all of these aspects into consideration, one can ensure a successful and reliable electrical connection.
