The 1.25mm pitch keeps the assembly compact, but that tight centreline also limits the wire gauge the crimp terminals can handle; you will be working with fine-gauge signal wire, not power conductors. ## The One Thing You Must Order Separately This housing ships with no contacts. That is not a packaging oversight — it is because the crimp terminal is a separate line item, selected by wire gauge and plating. The Micro-Lock PLUS terminal family includes tin and gold options; the gold-plated version is the one to reach for if the assembly will see repeated mating cycles or a corrosive environment. Without the terminal, the housing is just a plastic shell — the BOM line is incomplete until you add the correct Molex crimp contact part number for your wire size. The latch holder is the defining retention feature here. Unlike a ramped friction latch that can back out under cable strain, the Micro-Lock PLUS latch engages with an audible click and requires a deliberate lift to release. That makes this housing a good fit for harnesses that route through a moving assembly or see occasional tugging.","metaTitle":"Molex 5055651501 Micro-Lock PLUS Receptacle, 1.25mm Pitch","metaDescription":"Molex 5055651501 Micro-Lock PLUS 1-row receptacle housing, 1.25mm pitch, latch holder, -40°C to 105°C.
