What it is and where it sits in the series
The Molex 444412006 is the 6-circuit member of the Sabre 44441 family — a single-row, free-hanging receptacle housing at 0.295" (7.50 mm) pitch, designed to accept female blade socket contacts via crimp termination. The housing is black polyamide (nylon) and uses a latch-lock fastening to retain the terminals against vibration and mechanical disturbance in the harness. Side-to-side stacking is supported within the series, so multiple housings can be banked together on the wire harness without additional hardware.
What the ratings mean for the fit
The 18 A per circuit current rating is the primary decision point — at 7.50 mm pitch this positions the Sabre 44441 as a power-interconnect housing rather than a signal-density play. The 18 A figure applies per contact at the operating temperature limit of 75 °C; derate accordingly for sustained high-current runs to stay within the thermal ceiling of the nylon housing. The -40°C lower limit covers cold-start and outdoor industrial environments without a wide-temp grade, so confirm the harness routing does not approach the upper bound continuously. The 0.295" (7.50 mm) pitch sets the board footprint and wire harness bundle diameter. The latch lock keeps the terminal seated in high-vibration applications — industrial automation, HVAC control, and mobile equipment are the natural homes for this housing.
Contacts — order them separately
The listing explicitly notes Contacts Not Included. The housing accepts female blade socket terminals; the matching Molex crimp contact series for this family is the line item to find and add to the BOM. Skipping this step is the most common mis-order on housing-only listings — confirm the terminal series before quoting the housing.
