PCB Headers

A printed circuit board (PCB) header is a type of electrical connector.

What is a PCB header?

PCB headers are devices that enable the user to make multiple electrical connections to a PCB using one connection block or cable. They can also transfer signals from one PCB to another. Typically, one side of the PCB header connector is comprised of a series of pins that are soldered to the PCB surface at a right angle or parallel.

Different PCB header types have various applications which determine their size, weight and power. A PCB header designed for a cell phone will be very different to one used in a car, for example.

What are the common PCB header types?

PCB headers are made in both socketed - where the connections are housed in a plastic case - and non-socketed pin header types. Socketed PCB header connectors are more robust and less likely to cause short circuits but take up more space on the PCB. Non-socketed pin headers, by contrast, are easier to work with and suit a wider range of applications.

• Single or double row pin headers: The most commonly used types of PCB header are single or double row pin headers. These are produced in matching male (also known as PCB pins) and female versions (referred to as PCB receptacles) and are made from folded sheet metal with a square cross-section.


• Machine-pin headers: This variant has a circular cross-section which fits more precisely into round PCB holes and provides a better electrical connection, greater durability and an increased lifespan. They’re usually more expensive than single or double row pin headers.
