Product details

2-Position Free-Hanging Receptacle for Mini-Fit Jr Wire Harnesses

To build a complete harness, order the matching Mini-Fit Jr female crimp terminals (e.g., the 45750-series or 44476-series socket contacts) separately. 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.
