What the 444412004 is
The Molex 444412004 is the 4-circuit black receptacle housing in the Sabre 44441 series — a free-hanging, latch-lock body that accepts female blade socket crimp contacts at 7.50 mm pitch.
Contacts not included — the procurement action
The housing ships without contacts; the 18 A per-circuit rating belongs to the compatible female blade socket crimp terminals, which are ordered separately from the housing BOM line. Buying only the housing and expecting contacts inside is the most common mis-order on this series — one contacts-not-included note separates a complete assembly from a shell.
Fit, rating, and field-service reality
The latch lock on the housing body snaps over the matching tab on the plug — audible confirmation in the field, so what's really failing here is usually the tab fatigue or a backed-out contact rather than the housing itself. The 1-row, side-to-side stacking direction means this is a single-level circuit run; no mezzanine or stacked multi-row routing. Rated operating temperature is -40°C to 75°C — adequate for most industrial floor and harness bay environments, though the polyamide (nylon) insulation softens toward the upper bound if the connector runs near a heat source. PA/nylon is the right choice for oil-durability in machine-tool zones. The black housing is standard across the Sabre series; if colour-coding a harness split is required, confirm the position count matches before swapping to a different housing in the same family.
Compliance and sourcing
The 444412004 carries ROHS3 compliant status — no REACH or UL listing is present on this specific entry, so for CE-marked equipment confirm the full system-level documentation requirement with your compliance team.
