Molex MX64 0314049131 — 8-Pin Sealed Receptacle Housing, 2.54mm Pitch
The housing is black, molded from glass-filled PBT, and carries a Connector Position Assurance (CPA) latch plus a secondary lock feature — both tell you this was designed for automotive or industrial environments where a half-mated connector is a warranty call.
What the Sealing and CPA Mean for the Fit
The 'Sealed' feature means the housing has integrated interfacial and wire-entry seals — when mated with the corresponding MX64 plug and proper crimp terminals, the assembly meets IP ratings for splash and dust ingress. The CPA latch locks the mating halves together after engagement and provides a positive tactile confirmation that the connector is fully seated. In a harness build, the CPA prevents the connector from backing off under engine vibration or thermal cycling. The latch holder fastening type is the primary retention; the CPA is the secondary lock that catches if the primary latch isn't fully home.
The most important procurement detail on this page: the housing ships empty. Confirm the terminal part number with the MX64 series documentation before placing the BOM — ordering the housing alone leaves you with a connector that can't be wired.
