40 Pin Female Header Single Row

The 40 Pin Female Header Single Row Black is a dependable and widely used socket connector designed for clean, reusable electrical connections in prototyping and final circuit assemblies. With 40 high-quality sockets arranged in a single row at a standard 2.54mm (0.1 inch) pitch, this female header is compatible with a wide range of male header pins, microcontroller modules, and PCBs.

Manufactured using thermally stable black thermoplastic housing and tin-plated brass contacts, this header offers excellent mechanical strength and electrical reliability. The through-hole design allows secure soldering onto PCBs, making it ideal for both temporary testing setups and permanent installations.

This female header is particularly suited for Arduino shields, Raspberry Pi HATs, ESP32 modules, STM32 development boards, and general-purpose breakout boards. It is easily cut into smaller sections to match your specific pin requirements without compromising the contact quality.

Whether you’re assembling a one-off prototype or scaling up a production build, this 40 Pin Single Row Female Header provides a consistent and professional interface. Available now from eleberric.com, Sri Lanka’s trusted supplier for electronics components and accessories.
