40x2 10mm 2.54mm Pitch Female Pin Header

The 40×2 10 mm 2.54 mm Pitch Female Pin Header is a dual-row through-hole connector designed for stacking and interfacing PCBs with extended height clearance. Featuring 80 female contacts arranged in two rows with standard 2.54 mm spacing and a 10 mm body height, it is ideal for applications where components or boards need to be connected with vertical separation. This header is widely used in development boards, shield stacking, and modular electronic assemblies.
