Receptacle Housing for Micro-Lock PLUS Harnesses
It uses a 1.25mm pitch and a dual-row layout, with a latch holder fastening system that locks the housing to the mating header for vibration-resistant retention. This is a housing-only part — contacts are not included. The crimp termination style and free-hanging mount mean this housing is typically used as the cable-side half of a Micro-Lock PLUS interconnect, mating with the corresponding right-angle or vertical through-hole headers on the PCB.
What the 1.25mm Pitch and Dual-Row Layout Mean for Your Build
The 1.25mm pitch is the defining footprint dimension — it determines the header pin spacing on the PCB and the wire pitch in the harness. At this pitch, the dual-row 14-position layout gives a 7×2 arrangement, which keeps the connector body compact for tight cable routing. For field service, the latch can be released with a small flat-blade tool to unmate the housing without damaging the header pins.
Compatible Contacts and Mating Headers
The 5054321401 accepts female socket crimp terminals from the Micro-Lock PLUS terminal family. The exact Molex order code for the terminal depends on the wire gauge — typically 24-30 AWG for this series. The housing mates with Micro-Lock PLUS 505432 series headers, which are available in vertical and right-angle orientations with through-hole or surface-mount tails. The 14-position header order code follows the same base number pattern (505432 prefix) with a different suffix for the pin configuration.
