40x2 2mm Female Pin Header

The 40×2 2.0 mm Female Pin Header is a dual-row socket header designed for compact, high-density PCB connections. With a 2.0 mm pitch and 80 total contacts arranged in two parallel rows, it is ideal for modern microcontrollers, embedded modules, and board-to-board interconnections where space savings are critical. The female socket design allows secure and repeatable mating with corresponding male pin headers while maintaining a clean, professional PCB assembly.
