Sealed 12-Position Housing for Harsh Environments
The Molex MX150 1601116003 is a 12-circuit receptacle housing from the MX150 160111 series, built for sealed wire-to-board or wire-to-wire interconnects in environments where moisture and temperature extremes are the norm. The glass-filled nylon 6 housing (PA6) handles the mechanical and thermal demands of a vehicle harness — impact resistance at cold start and dimensional stability at continuous underhood soak.
For a full harness build, you need the MX150 female crimp terminals — typically Molex 33001 or 33012 series, sized for the wire gauge your circuit demands. The 2-row, 12-position layout (6 circuits per row) means the terminal insertion sequence matters: seat all terminals in one row before starting the second to avoid cross-loading the housing cavities. Verify the header part number matches the MX150 160111 series and the same 3.50 mm pitch before ordering the mating half — the latch geometry is specific to this generation of the MX150 family.
