The ZW-09-13-F interconnect from Samtec is a through-hole board stacker header with a 2.54mm pitch, designed for stacking multiple PCBs together. These headers are commonly found in industrial control panels, test equipment, and medical devices where compactness and robust connections are crucial. If you're working on systems that require a high density of connections but also need to maintain mechanical integrity, these headers are a solid choice. One thing worth noting is their reliability; engineers tend to reach for Samtec's through-hole headers when they need to ensure long-term stability in environments with vibrations or frequent handling. Another practical benefit is their ease of assembly, thanks to the through-hole design, which makes them ideal for manufacturing lines where quick setup and production are key.
