It is an unshrouded, through-hole board-to-board interconnect with a 0.100" (2.54 mm) pitch on both rows and a matching row spacing of 0.100" (2.54 mm). The header is rated 5 A per circuit at 110 V, and the black PA6T housing carries a UL94 V-0 flammability rating. The overall contact length is 0.820" (20.83 mm), with a 0.360" (9.14 mm) mating length and a 0.360" (9.14 mm) post length for through-hole soldering.
The 0.100" (2.54 mm) pitch is a de facto standard for prototyping and dense signal routing — it matches common perfboard and 0.100"-pitch IDC ribbon cable patterns. The 0.360" (9.14 mm) post length is sized for standard 0.062" (1.6 mm) PCBs; it provides enough tail protrusion for a reliable solder fillet without bottoming out against a second board in a back-to-back stack.
