The Amphenol FCI 95687-124HLF is a 24-position, dual-row unshrouded header from the BERGSTIK II series, built on the standard 0.100" (2.54 mm) pitch for board-to-board interconnect.
The 0.100" pitch and 0.100" row spacing define a standard dual-row footprint — the same grid used by legacy IDC and DIP socket patterns, so the board layout matches a wide installed base. The 0.360" mating pin length and 0.360" post length give enough standoff for a shrouded receptacle or a second board in a mezzanine stack. The 5 A per-contact rating is a per-circuit limit at the rated voltage; for a 24-position header running all circuits simultaneously, the total current through the connector is the sum of the loaded circuits, each at 5 A, with derating above ambient temperature per the manufacturer's curve.
This is an unshrouded male pin header with a push-pull fastening system — it mates with any standard 0.100" pitch dual-row female socket or receptacle that accepts 0.025" square pins.
