The Molex MX150 1601126001 is a 12-position, 2-row sealed receptacle housing from the MX150 160112 series, designed for free-hanging (in-line) wire-to-wire or wire-to-board harness applications where moisture and vibration are present.
Sealed and ready for wet environments
This housing carries a sealed rating, meaning it incorporates integral interfacial and wire-entry seals that prevent water ingress when mated with the corresponding MX150 plug and fitted with the correct seal-plugged terminals. This makes the 1601126001 suitable for harness runs exposed to splash, pressure wash, or immersion — common in engine bay, battery pack, and lighting circuits.
Contacts are ordered separately — a common sourcing trap
For the MX150 series, the matching terminal is the Molex 33000-series or 33001-series crimp contact, sized for the wire gauge your circuit requires. Ordering the housing alone and forgetting the terminals is a frequent BOM miss — confirm both line items before committing.
This is not a friction-only fit — the ramp deflects over a matching shoulder on the plug and snaps into place, resisting un-mating from cable tug or machine vibration. For field-service techs, the ramp is also a quick visual and tactile confirmation that the connector is fully seated.
