The 40×2 20 mm 2.54 mm Pitch Gold Male Pin Header is a double-row, through-hole male connector designed for reliable board-to-board and module-to-board connections. With a standard 2.54 mm pitch and extended 20 mm pin length, it is ideal for stacking PCBs, shield connections, and applications requiring extra clearance. Gold-plated pins ensure excellent conductivity, corrosion resistance, and long-term reliability.
