Rectangular Connectors - Headers, Male Pins (4-102978-0-14)

Rectangular connectors – Headers, male pins are an important part of electronics components used in many industrial, commercial, educational, and military applications. They are commonly used to provide interconnection between circuits, allowing components to be added and removed without making physical changes to wiring. They frequently accommodate a variety of standard circuit configurations, cables, enclosures, and structural designs.

Application Field

Rectangular connectors are used extensively in industrial and consumer applications. Their reliable performance, durability, and wide variety of available configurations make them an ideal choice for a broad range of applications. They are frequently used to interconnect enclosures, control panels, electrical cables, chassis, and many other components.

Most rectangular connectors feature a 3.81mm or 5.08mm centerline spacing which allows them to accept pins from a variety of common sizes and shapes including round pins, square pins, flat ribbon cable terminals, and PC boards. This wide range of compatible connectors and pin sizes makes them useful in many environments.

In addition, they are often used for telecommunications equipment, aviation systems, medical equipment, electronic instruments, electronic test and measurement equipment, and computer systems.

Working Principle

Rectangular connectors use a two-part, interlocking system typically with an internal receptacle and an external housing. The housing consists of two interlocking pieces that snap together to cover and secure the internal components. The internal components include the contacts and pins designed to create an electrical connection when the connector is mated with another contact.

The contacts and pins are typically made of copper or brass and they are often plated with a corrosion resistant material. This ensures a reliable connection even in the presence of high humidity and corrosive environments. In addition, high temperature-resistant components are also available for applications where extreme temperatures are encountered.

When two connectors are mated, they create a secure and water-tight electrical connection that is capable of withstanding high voltage and high current. This is why rectangular connectors are often used in automotive, industrial, and military applications. Additionally, because they are waterproof, they are frequently used in medical, aerospace, and marine applications as well.

In conclusion, rectangular connectors – Headers, male pins are an important part of electronics components used in many applications. They are reliable, durable, and corrosion resistant, making them a great choice for a wide range of industries.
