What this sealed receptacle is built for
The Molex 0194180001 is an 8-circuit, 2-row receptacle from the MX150L 19418 series, designed for sealed wire-to-wire interconnects where moisture and vibration are the main threats to uptime. The housing is free-hanging (in-line), terminated by crimping the appropriate female socket contacts into the wire and inserting them into the cavity.
Sizing the BOM line — contacts and mating half
The mating half is the MX150L 19418 series male plug header, also IP67-rated with the matching CPA latch. The 8-circuit count and 5.84mm pitch must match on both sides — a 6-circuit or 10-circuit plug will not seat, and the keying ribs in the housing prevent cross-mating with other MX150L position sizes.
Sealing and retention — what IP67 and CPA mean on the bench
The IP67 rating means the mated pair withstands immersion in 1m of water for 30 minutes — not just splash or hose-down. That seal comes from the interfacial seal between the plug and receptacle faces, plus individual wire seals on each cavity. The CPA latch is a secondary lock that slides over the primary latch after mating, preventing the latch from being depressed even under cable strain or vibration. The tray packaging suits hand-assembly lines where the housing is picked and loaded into a fixture for terminal insertion.
