The 0.100\" (2.54mm) pitch on both rows and between rows matches the standard 0.1-inch grid, making it a direct fit for legacy and current PCB layouts that use this spacing. With all 50 positions loaded, this header provides a full complement of square pins for dense signal or low-power distribution. The overall contact length of 0.410\" (10.41mm) comprises a 0.190\" (4.83mm) mating length and a 0.120\" (3.05mm) solder tail. The through-hole termination requires a PCB with 0.025\" to 0.030\" plated-through holes on a 0.100\" grid. Contacts are phosphor bronze with tin plating. The base product number is 79425, and this variant (450) denotes the specific plating and tail length combination.","metaTitle":"79425-450HLF BERGSTIK® II Header, 50-Pos, 2.54mm Pitch, 5A","metaDescription":"79425-450HLF BERGSTIK® II unshrouded header, 50 positions, 0.100\" pitch, rated 5A at 110V.
