Micro Quadlok Receptacle Housing for Mixed Signal-Power Harnesses
The 1379217-3: It is a free-hanging (in-line) housing that accepts female socket terminals — the contacts are ordered separately. The locking ramp fastening keeps the mated pair together under vibration, and the glass-filled PBT insulation handles -40°C to 100°C operating temperatures, making it suited for automotive underhood, industrial cabinet, and small-engine harness applications where you need a compact mixed-power interconnect.
Position Layout and Mating Half
The 5-position layout (3 + 2 power) is the key differentiator in the Micro Quadlok family. The 1379029-1 is a 4-position receptacle with no dedicated power contacts and uses a latch lock instead of the locking ramp. The mating header for this housing is the corresponding Micro Quadlok pin header with the same 5-position, 3+2 contact arrangement.
Terminal Selection and Assembly
The housing ships without contacts — the note 'Contacts Not Included' is not a warning, it is the standard practice for Micro Quadlok receptacles. You select the female socket terminal separately based on your wire gauge and current requirements. The locking ramp engages with a positive click when mated to the header; give it a tug to confirm the latch has seated before routing the harness into the enclosure.
