What this 2-position Micro-Lock PLUS header is for
The 5055680231: This is a 2-circuit, single-row, surface-mount header from the Molex Micro-Lock PLUS 505568 series. The 1.25 mm pitch and 7.4 mm mated stack height target board-to-cable applications where space is tight — think automotive interior modules, industrial sensors, or general-purpose signal interconnects that need a positive lock.
Current rating and what it depends on
For the Micro-Lock PLUS series, expect 1-2 A per circuit with 28-30 AWG wire in a typical signal application; the 15 µinch gold mating surface keeps contact resistance stable over repeated cycles.
Mating half and build-to-print BOM
This header mates with the Micro-Lock PLUS receptacle housing (Molex series 505567) and requires the matching crimp terminals (Molex 505566 series). For a complete build-to-print assembly, you need the header, the receptacle, and the terminals — all three are sold separately.
