Plug Housing for Sealed, Vibration-Resistant Harnesses
The Molex 2042230004 is a 4-circuit plug housing from the Squba 1.8 series, built for wire-to-board or wire-to-wire interconnects where a sealed, locking connection is needed. The 1.80 mm pitch keeps the footprint compact while the locking ramp holds the pair mated under vibration — a common requirement in automotive, industrial, and outdoor power distribution harnesses.
What You Need to Order: Contacts Are Sold Separately
This is a housing only — the crimp terminals (male pins) are not included and must be ordered as a separate line item. The 4 circuits accept the Squba 1.8 male crimp terminals (Molex series 204223), which are terminated to the wire before insertion. The housing's single-row layout and free-hanging (in-line) mount make it straightforward to assemble into a harness; the locking ramp gives a positive audible click when fully mated with the matching receptacle.
Sealed Construction and Material Choice
The housing is molded from polyamide (PA) nylon in black, and it carries a sealed rating — meaning the mated connector pair resists moisture and dust ingress, suitable for washdown or outdoor exposure. The locking ramp fastening type adds mechanical security beyond a simple friction fit, so the connection stays mated under cable strain or machine vibration.
