The Molex 0009484049 is a 4-circuit, single-row receptacle from the KK396 family (also grouped under the 41815 series). It uses a 3.96 mm pitch — the same footprint as the classic KK.156-inch headers — and terminates via through-hole solder to the PCB.
Rated 4.5 A per circuit at 600 V, the 0009484049 sits in the light-power band of the KK396 range — enough for a sensor supply, a small solenoid, or a low-current board interconnect, but not a bus-level power rail. The 3.96 mm pitch gives enough creepage to hold the 600 V rating without forcing an oversized board footprint, and the tin plating (60.0 µinch on both mating and post sides) is a good match for moderate mating-cycle applications where cost per position matters more than cycle life.
