What this connector is
The 87900-148HLF is the 48-circuit member of Amphenol ICC's BERGSTIK II series — a dual-row unshrouded male header designed for through-hole board-to-board stacking at 0.100 inch (2.54 mm) pitch. With 5 A per circuit at 110 V and 30 µin gold-plated contacts on a phosphor bronze body, it sits at the mid-quality tier of the BERGSTIK line, suited for signal distribution and low-power interconnects in industrial control, instrumentation, and communications equipment.
What the key ratings mean
48 positions across two rows gives a 24-by-2 layout — the largest standard circuit count in the BERGSTIK II family before moving to multi-column arrangements. At 5 A per contact this header handles low-level power distribution comfortably, but the 110 V ceiling keeps it in signal and control territory rather than any high-voltage bus. The 30 µin gold plating over nickel on the mating surface provides reliable wipe durability and oxidation resistance for extended field service, and the UL94 V-0 insulator means the housing material will not support combustion — important for enclosed equipment racks and industrial enclosures.
