What are pin headers?
Meet the Connector: Pin Headers
Pin headers are a type of electrical connector that consists of one or more rows of metal pins or contacts molded into a plastic base. They serve as a bridge between various elements in an electronic device, enabling the distribution of power, data, and signal throughout a device. They can connect printed circuit boards (PCBs) to each other or connect a PCB to a breadboard or other prototyping device.Pin headers are available in a variety of sizes and configurations, including straight or right-angle, with the most common pitch being 2.54 mm (0.1 inches). Pin headers are typically soldered to the PCB, but they can also be press-fit into connectors that are designed for that purpose.
These versatile, economical, and easy to use interconnects serve a wide variety of applications, including consumer electronics, industrial automation, automotive, aerospace and defense, medical devices, and IoT devices. Pin headers are a solid choice for simple connections, such as a microcontroller board to a breadboard; a sensor to a PCB; a PCB to a backplane; a display to a PCB; or a motor to a PCB.
Pin headers are one of the connector types that engineers are likely to encounter early on as they develop interest in the field. Pin headers are featured in development boards such as Arduino and Raspberry Pi as the connector used to attach peripheral units such as displays, sensors, and expansion modules. They are also in prototyping and custom electronics.
Pitch: The 2.54 mm (0.1-inch) pitch is the most common pin header. However, other pitches, such as 1.27 mm (0.05 inches) and 2.00 mm (0.079 inches), also exist for specialized applications.
Number of Rows: Pin headers can have single or double rows of pins. Single-row headers are common for simpler connections, while double-row headers provide more connections in a smaller space.
Pin Length: Standardized pin lengths ensure that pin headers are compatible with different PCB thicknesses. Common lengths include 4.5 mm, 5 mm, and 6 mm.
Pin Diameter: Pin headers typically have standardized pin diameters to ensure a secure and reliable connection.
Mounting Options: Pin headers can be available in various mounting options, including through-hole (for PCBs) and surface mount (SMT) versions, allowing for flexibility in design.
