Description
40x1 20mm 2.54mm Male Pin Header
The 40×1 20 mm 2.54 mm Male Pin Header is a single-row, straight through-hole connector designed for extended pin reach and secure PCB interconnections. With a longer 20 mm pin length and standard 2.54 mm pitch, it is ideal for stacked boards, deep sockets, and applications requiring extra clearance. The robust plastic spacer ensures precise alignment and long-term reliability.
