40 Pin Straight Female Header Pins - Berg Strips

2.54 mm Female Headers - Single and Dual Row PCB Connector

The Female Header is a fundamental interconnection component in electronics prototyping and manufacturing, serving as the socket for male header pins. These headers are essential for creating modular, removable connections between development boards (like Arduino or Raspberry Pi), shields, and various sensor modules. This standard version features a 2.54 mm (0.1 inch) pitch, which is the universal standard for breadboards and through-hole components.

Available in various configurations, the most common being single-row (1x40) and dual-row (2x40) strips, these headers can be easily cut to size using side cutters to perfectly match the pin count of any module or daughterboard. The construction features a durable plastic housing and high-quality metal sockets, ensuring excellent mechanical strength and reliable electrical contact over many mating cycles. They are typically vertically mounted and soldered permanently into a PCB, providing a secure and flexible interface.
