Rectangular Connectors - Headers, Male Pins

Rectangular connectors with headers and male pins are versatile electrical connectors commonly used for a variety of applications. These connectors can be used in a variety of circuit board positions to provide electrical and mechanical connectivity between two circuits, a circuit and a device, or between two devices. The popularity of this type of connector is a result of its physical design combined with its reliable electrical characteristics.

2-102617-3 Application Field and Working Principle

The 2-102617-3 rectangular connectors with headers and male pins are typically used in hot-swap applications that require frequent plugging and unplugging of external equipment. It is a common choice for audio components, test equipment, instrumentation, industrial controls, telecommunications equipment, and all types of power supplies. The 2-102617-3 is a two-piece connector, with a header and male pin. The header has sockets for two miniature pins and is mounted onto a printed circuit board, while the male pin is placed into the header sockets with a mating force.

Once plugged in, the header and male pin contact each other, which allows electricity to flow from one component to the other. The contact between the two connectors is made when the mating force pushes the male pin into the respective sockets of the header. The contact point between the header and the metal male pins is based on a ferrule effect that is created from the header’s ergonomic design.

The ferrule effect ensures a reliable electrical connection is made even when the mating force is not strong enough to completely recess the male pins into the header. This is essential for high-power applications, where the potential for arcing is critical for achieving a good electrical connection.

The 2-102617-3 rectangular connectors with headers and male pins are designed to provide strong electrical connectivity and are especially well-suited for applications that require frequent plugging and unplugging of external equipment. Its ferrule effect ensures reliable electrical connection even when the mating force is not strong enough to completely recess the male pin into the header. This makes them an ideal solution for hot-swap applications as well as a variety of other applications.
