MX150 Sealed Receptacle for Harsh-Environment Harnesses
The Molex 334724103 is a 4-circuit, 2-row receptacle from the MX150 33472 series, designed for sealed wire-to-board or wire-to-wire interconnects where moisture and temperature extremes are the norm. Gray housing — standard color for this position count in the MX150 family — makes it visually distinct during harness assembly.
This is a female socket receptacle that accepts MX150 crimp terminals (sold separately). The free-hanging (in-line) mounting style suits it for harness runs where the connector floats rather than being panel-mounted. The latch holder must be in the open position during insertion; it is closed after all circuits are loaded to lock the terminals in place. For a 4-circuit build, this is a fast, repeatable process — no soldering, no post-mold.
The functional peer 33472-4103 shares the same spec set (gray, 4-circuit, sealed, 3.50mm pitch, crimp termination) and is a direct alternative for BOM matching.
