What Are Pin Header Connectors?

In the realm of electronic components, pin header connectors play a crucial role in establishing reliable and efficient connections between various circuit boards and electronic devices. These small but mighty connectors are designed to provide a secure and robust interface, enabling the transfer of signals, power, and data between different components. In this blog post, we will delve into the world of pin header connectors by discussing their types and advantages.

Understanding Pin Header Connectors

Also known as board connectors, pin header connectors are compact electronic components that consist of a row of pins or terminals arranged in a plastic or metal housing. Upon installation, they are commonly used in electronic devices and circuit boards to establish a reliable electrical connection. Apart from thriving in the electronics and telecommunications industries, pin header connectors also find use in automotive, aerospace, and other sectors.

Types of Pin Headers

  • Single Row Pin Header: Typically designed in a straight configuration, this type consists of a single row of pins and are widely used for connecting peripheral devices, such as sensors, LCD displays, and other modules, alongside main PCBs (Printed Circuit Boards).

  • Double Row Pin Header: Double row pin headers feature two parallel rows of pins, providing a higher pin count and increased connectivity options. For this reason, they are frequently used for applications that require a greater number of connections, such as expansion boards or complex circuitry.

  • Insulation Displacement Connectors (IDCs): IDCs are a type of pin header connector that allow for easy and efficient mass termination of flat cables, like ribbon cables. Their sharp contact or blade displaces the insulation of the cable when it is inserted into the connector. As such, IDCs are widely used in applications where a large number of electrical connections need to be formed quickly and reliably, such as telecommunications and data centers.

  • Crimp Connectors: Designed for applications where cables or wires need to be securely attached to the connector, crimp connectors feature pins with crimpable terminals, those of which are attached to the wires using a crimping tool. More than that, the reliable and durable connections they establish make them suitable for applications with high vibration or movement.


  • Versatility: Pin headers offer versatile connectivity options by permitting different types of connectors to be easily attached or detached. Such flexibility enables easy customization and adaptability to various circuit board layouts and configurations.

  • Secure Connections: Pin header connectors provide a secure and stable connection between components, ensuring reliable signal and power transmission. In addition, their mechanical locking mechanisms or friction-based designs prevent accidental disconnections and enhance overall system integrity.

  • Space Efficiency: Pin headers are compact and space-efficient, thereby making them suitable for applications with limited board space. They also enable high-density PCB layouts and allow for efficient use of available real estate.

  • Ease of Assembly: Designed for easy assembly, pin headers are ideal for mass production and automated assembly processes, which simplifies the installation and removal of components and reduces manufacturing time and costs.


Pin header connectors are essential components in the world of electronics, enabling seamless and reliable connections between circuit boards and electronic devices. With their versatility, secure connections, and space efficiency, pin headers have become indispensable in a wide range of industries. Whether it is single-row or double-row headers, IDCs, or crimp connectors, understanding the different types is pertinent to efficient circuit board design and interconnection.
