A 40-Pin Female-Male Header is an electronic connector consisting of two rows of pins, with one row being female and the other male. These headers are commonly used for connecting and extending connections between two circuit boards or components, enabling secure and versatile electrical connections. 40-pin female-male headers are versatile connectors used in various electronic applications to establish connections between PCBs or components. They are commonly found in development boards, expansion boards, and prototyping environments to facilitate easy and detachable connections while ensuring a secure electrical link.

Specifications:

• Pin Count: Typically consists of 40 pins (20 pins in each row), but headers with different pin counts are also available.
• Gender: Features one row of female sockets (usually on the bottom) and one row of male pins (usually on the top).
• Pitch: The distance between adjacent pins, known as the pitch, is typically 2.54 millimeters (0.1 inches), which is a standard pitch used in many electronic applications.
• Contact Material: The pins are usually made of metal, such as brass or phosphor bronze, to ensure good electrical conductivity.
• Insulation Material: The header body is often made of plastic or nylon, providing electrical insulation and mechanical support.
• Mounting: Designed for through-hole mounting on a printed circuit board (PCB), allowing for secure and soldered connections.
• Applications: Widely used in electronics and PCB design to create removable connections, facilitate board stacking, or extend connections between circuit boards or components.
• Header Types: Apart from female-male headers, other common header types include male-male headers, female-female headers, and right-angle headers, each serving specific connection needs.
• Connector Length: The length of the connector body can vary, with longer headers providing more stability and spacing between boards.
