The 2-position count means a harness builder needs exactly 2 terminals per housing, plus the mating male header or plug housing for the other half of the interconnect. ## Mating Half and Polarization The recommended mating connector for this receptacle is a Molex Mini-Fit Jr male header or plug housing with the same 2-circuit, dual-row, 4.20mm pitch layout. The housing is polarized by the keying geometry of the Mini-Fit Jr interface, preventing mis-mating with other series or reversed orientation.","metaTitle":"Molex Mini-Fit Jr 0039012020, 2-Position Receptacle Housing","metaDescription":"Molex 0039012020 Mini-Fit Jr 5557 receptacle, 2 circuits, 4.20mm pitch, latch lock, -40°C to 105°C.
