The push-pull fastening type means it latches without tools, but the latch is positive enough for vibration environments typical of automotive and industrial use.
When mated with the Micro-Lock PLUS receptacle, the stack height is 7.4 mm — a fixed dimension that determines the z-axis clearance inside your enclosure. The header is rated for 50 VAC/DC.
The mating connector is a Micro-Lock PLUS receptacle housing (crimp type) from the same 505568 series, with 3 positions and 1.25 mm pitch. Use the corresponding Molex crimp terminals for your wire gauge.

The current rating is listed as varying by wire gauge. In practice, the header pin itself is not the bottleneck — the limiting factor is the wire size and the crimp terminal's rating. For a given wire gauge, refer to the Micro-Lock PLUS terminal datasheet.
