The tin-plated mating surface (100.0 µin / 2.54 µm) and phosphor bronze contacts are rated for 5 A per circuit at 110 V, which covers signal-level duty and moderate power distribution within a single backplane or daughtercard. The 0.100\" (2.54 mm) pitch and 0.100\" (2.54 mm) row spacing are the de facto standard for prototyping and legacy bus architectures — your board footprint is a simple 0.100\" grid, which keeps routing straightforward on a two-layer PCB. The overall contact length of 0.990\" (25.15 mm) and a mating length of 0.770\" (19.56 mm) mean the header stands tall enough to reach a receptacle in a mid-plane stack-up. The BERGSTIK II series is a broad family; the 87052 base number covers dual-row, unshrouded headers in various pin counts and plating options.","metaTitle":"Amphenol BERGSTIK II 87052-434HLF, 34-Pin Header","metaDescription":"Amphenol BERGSTIK II 87052-434HLF unshrouded male pin header, 34 positions, 0.100\" pitch, 5 A, 110 V, tin-plated, UL94 V-0.
