Board Fit and Wire Gauge Ceiling
The 1744017-2: The 3.96mm pitch on this 2-position header sets the board footprint wide enough for 18-22 AWG power wiring but rules out dense signal routing — you're not cramming this into a tight logic board. The single-row layout with all positions loaded keeps the BOM simple: one header, two pins, one mating half.
Friction Lock vs Vibration Duty
The friction lock keeps the mating housing from backing off under casual vibration — think a control cabinet door being opened and closed, not an engine mount. There's no secondary TPA or detent, so in high-shock environments you'd want a positive latch or a cable tie around the pair.
Temperature Range and Envelope
Fine for a ventilated industrial panel or a general-purpose enclosure; not for an engine bay or a hot plenum where the ambient pushes past 105°C.
