Pin Header Connector

A pin header connector, also known as a header, is a type of electrical connector commonly used in electronic devices, including automotive applications. Here are the key features and uses of pin header connectors:

1. Design:
– Consists of a row or array of metal pins, typically made of brass or copper, protruding from a plastic or insulating base.
– The pins are arranged in a grid pattern, with a specific number of rows and columns.
– The pins are spaced at a standardized pitch, usually 0.1 inches (2.54 mm) or 0.156 inches (3.96 mm).

2. Applications:
– Commonly used to establish connections between printed circuit boards (PCBs), such as connecting a PCB to a motherboard or other peripheral devices.
– Utilized in various electronic devices, including computers, industrial equipment, and automotive electronics.
– Provide a reliable and compact way to transmit power, data, and signals between components.

3. Mating Connectors:
– Pin headers are designed to mate with female socket connectors, also known as receptacles or headers.
– The socket connectors have corresponding holes that the pins can be inserted into, forming a secure and reliable connection.
– This allows for easy assembly, disassembly, and replacement of components.

4. Keying and Polarization:
– Pin headers may have polarizing features, such as a specific pin arrangement or the presence of a key, to ensure correct orientation and prevent improper mating.
– This helps to prevent damage to the components and ensures the correct signal and power connections are made.

5. Customization and Variations:
– Pin headers are available in various sizes, ranging from single-row to multiple-row configurations.
– They can be straight, right-angled, or have other specialized shapes to accommodate different space requirements and mounting orientations.
– Specialized versions, such as shielded or high-density pin headers, are also available for specific applications.

In the automotive industry, pin header connectors are widely used to connect electronic control units (ECUs), sensors, and other electronic components within the vehicle’s electrical system. Their modular design and standardized dimensions make them a versatile and reliable choice for establishing connections in the harsh automotive environment.
