The Molex 0348994075 is a 1.2 mm pitch, single-row blade assembly with 4 circuits, identified by a yellow keying color. The description '1.2MM SLD ASSY BLD 1X4 7CS YEL K' indicates a solid blade design, likely used in wire-to-board or board-to-board power distribution within compact electronic assemblies. The 1.2 mm pitch suits dense PCB layouts where space is at a premium, typical in consumer electronics, small appliances, or automotive interior modules.
The 1.2 mm pitch allows for a compact footprint, while the single-row, 4-circuit configuration matches low pin-count signal or low-power connections. The yellow keying provides polarization to prevent mis-mating with differently keyed housings. Supplied in Bag packaging, this part is suited for manual assembly or low-volume production runs.
This blade assembly mates with a corresponding Molex receptacle housing of the same 1.2 mm pitch series, also with 4 circuits and matching yellow keying. The keying color ensures correct orientation and prevents cross-mating with other variants in the series. The Base Product Number 034899 groups this with other pitch and circuit-count options for the same family.
