Pin headers and socket headers are commonly used electronic connectors for signal transmission and power supply between circuit boards or devices. A pin header is a connector with pin-shaped leads, typically soldered onto a circuit board, and is designed to be inserted into a socket header. A socket header, on the other hand, is a connector with hole-shaped slots meant to receive the pin header, facilitating signal transmission and power supply.

Pin and socket header connectors are often used for internal connections in electronic devices, such as connections between computer motherboards and expansion cards, as well as connections between various sensors and controllers. They offer reliable connection performance and good anti-interference capability, making them suitable for various industrial and commercial application scenarios.
