What is the pin header connector? Its types, working, advantages, disadvantages & Applications

A pin header connector is a type of electrical connector commonly used to connect two printed circuit boards (PCBs) together or to interface other components with a PCB. It is made up of plastic housing and multiple pins or contacts arranged in a linear or rectangular pattern. Here is some information about pin header connectors.

Types of pin header connector:

  • Single-row pin header connector: has one row of pins.
  • Dual-row pin header connector: has two rows of pins.
  • Surface mount pin header : designed to be mounted directly onto a PCB surface.
  • Through-hole pin header: has pins that go through holes in the PCB and are soldered on the other side.
  • Right angle pin header connector: has pins that are bent at a 90-degree angle and are suitable for use in tight spaces.

Working of pin header connector:

A pin header works by connecting pins on one PCB with corresponding pins on another PCB or component. The pins on one end of the connector are inserted into the corresponding holes on one PCB and are soldered in place. The other end of the connector is then plugged into the corresponding holes on the other PCB or component, providing a secure electrical connection.


  • Easy to connect and disconnect, which makes them suitable for use in applications where PCBs need to be frequently replaced or updated.
  • Can accommodate a large number of pins in a compact space.
  • Provides a secure and reliable electrical connection.
  • Can be used with both through-hole and surface mount PCBs.


  • May require a separate mating connector, which can add cost and complexity to the system.
  • May not be suitable for use in high-vibration environments, as the pins may become loose over time.


  • Used in various electronic devices, such as computers, printers, and consumer electronics.
  • Used in industrial automation and control systems.
  • Used in medical devices and scientific equipment.
  • Used in automotive electronics and aerospace applications.
