The housing material — a blend of glass-filled nylon (PA) and syndiotactic polystyrene (SPS) — holds dimensional stability across that swing, so the terminal retention doesn't loosen when the engine bay cycles from freezing to hot soak. ## Mating Half and Harness Planning This receptacle mates with the MX150 34985 series plug header (e.g., 0349851161 or similar 16-circuit plug). For a full harness, order the receptacle housing, the plug housing, and the crimp terminals (female sockets for this side, male pins for the plug) as separate line items.","metaTitle":"Molex MX150 34985 0349852121, 16-Circuit Sealed Receptacle","metaDescription":"Molex MX150 34985 series 0349852121 receptacle, 16 circuits, dual-row, sealed, gray housing, -40°C to 125°C.
