Mounting is panel-mount snap-in, so the housing clips into a cutout without hardware, and the crimp termination means the user selects and installs the terminals separately. ## Contacts Not Included — What Fits This housing accepts the standard Mini-Fit Jr male crimp terminals, which are ordered separately as Molex 5556 series pins. The 20-position count means a full harness requires 20 individual pin terminals plus the mating receptacle housing and its female terminals. The crimp termination suits automated or bench-top harness tooling — the terminal is inserted from the rear and retained by the housing's internal lance, with the locking ramp securing the mated pair. ## Rated for the Environment","metaTitle":"Molex 0039012201 Mini-Fit Jr 5559 Plug Housing, 20 Pos","metaDescription":"Molex 0039012201 Mini-Fit Jr 5559 20-position dual-row plug housing, 4.20mm pitch, locking ramp, panel mount.
