It is a free-hanging (in-line) crimp-style housing meant for wire-to-board or wire-to-wire harness applications where a compact, positive-latching interconnect is needed. The natural PBT insulator carries a latch holder for secure mating retention, and the housing accepts non-gendered crimp contacts that must be ordered separately — the listing explicitly notes contacts are not included. The 1.25 mm pitch keeps the connector narrow enough for dense harness routing, while the single-row 4-position layout matches low-circuit-count signal and low-power applications. ## What the 1.25 mm Pitch and 4 Positions Mean for the Fit The 0.049\" (1.25 mm) pitch sets the header footprint. The latch holder resists vibration-induced disconnection.","metaTitle":"Molex 5041930400 Micro-Lock 1.25mm Receptacle Housing, 4 Pos","metaDescription":"Molex 5041930400 Micro-Lock 1.25mm receptacle housing, 4 circuits, natural PBT.
