4-Position Plug Housing for Wire-to-Wire Harnesses
The Molex 0019092049 is a 4-position plug housing from the 3191 series, designed for wire-to-wire interconnects where a positive-lock mate and a wide pitch keep the assembly serviceable. The natural PA66 housing carries a locking ramp that snaps onto the mating receptacle and holds under vibration — no secondary lock needed for most panel or chassis harness runs.
The free-hanging (in-line) mounting means the housing floats in the harness, so the locking ramp carries the retention load, not a panel clip.
