It uses a standard 0.100" (2.54 mm) pitch on both the pin-to-pin and row spacing, matching the legacy 0.100-inch grid that dominates through-hole PCB layouts.
The 5 A per circuit rating at 110 V is typical for a 0.100-inch pitch header of this density — the current is shared across 70 circuits, so the total board-level power is limited by the pin count and the temperature rise of the housing. The tin on the solder tails is standard for wave-solder assembly — no special flux or pre-tinning required.
Contacts are phosphor bronze — a common spring material that holds up to repeated deflection without taking a set. The BERGSTIK® II series is a broad family of 0.100-inch pitch headers; the 93939 base number covers the dual-row, right-angle variants with various position counts and plating options.
