Pinout and Pitch: The Footprint Decision
The 10114829-10110LF: The 4-wall shroud and detent lock mean the header is keyed and self-latching; it mates with a corresponding cable receptacle that has a matching latch ramp, so the pair won't separate under vibration without a deliberate pull.
Current and Voltage: Signal-Duty Ceiling
The tin-on-tin contact interface (mating and post) keeps contact resistance consistent for low-level digital or sensor signals, but derates quickly if you push the current above 1 A per pin.
RoHS compliant per current directive.
