Understanding the Product

A pin header plug is a type of electrical connector that features one or more pins protruding from a rectangular housing. Its primary function is to create secure electrical connections between circuit boards or between components on a board. Typically made from durable materials like plastic and metal, pin header plugs are designed to withstand frequent connections and disconnections, making them perfect for prototyping and production.

Characteristics of Pin Header Plugs

Pin header plugs come in several configurations, allowing for multiple uses across various applications. Here are key characteristics to consider:

  1. Pin Count: Pin header plugs are available with different pin counts, ranging from a couple of pins to dozens, catering to various needs.

  2. Pitch: The pitch, or the distance between pins, is another crucial factor. Standard pitches include 2.54mm (0.1 inches) and 1.27mm (0.05 inches). Depending on space constraints in your design, choosing the right pitch is vital to maintaining optimal functionality.

  3. Orientation: Pin header plugs are available in straight or angled configurations. Straight connectors are ideal for vertical connections, while angled connectors work well in applications with limited space.

  4. Material: The materials used in pin header plugs significantly influence their performance. High-quality metals such as gold or tin are often used for the pins, ensuring corrosion resistance and reliable conductivity.

  5. Mounting Style: Pin header plugs may be through-hole or surface-mounted, providing compatibility with various PCB designs.

Applications of Pin Header Plugs

The versatility of pin header plugs makes them suitable for a wide range of applications. Here are some key areas where you will commonly find them:
