This is the free-hanging (in-line) half of the connection, designed to accept crimp terminals and mate with a board-mounted Micro-Lock PLUS receptacle header. The single-row, 9-position layout keeps the harness narrow — useful when routing multiple circuits through a tight cable channel or along a PCB edge. ## Terminal Selection and Crimp Termination This plug housing accepts male pin crimp terminals (contact type: Male Pin). The 1.25mm pitch means the terminal pocket spacing is tight — use the correct Molex crimp tooling for the wire gauge range specified in the terminal datasheet to avoid terminal push-back or high-resistance crimps. No secondary position assurance (TPA) retainer is listed for this housing — the primary latch is the locking ramp itself. The 2145252091 mates with a Micro-Lock PLUS 1.25mm-pitch board-mounted receptacle header (the mating connector is not included with this housing).","metaTitle":"Molex 2145252091 Micro-Lock PLUS Plug, 9 Circuits","metaDescription":"Molex 2145252091 Micro-Lock PLUS single-row plug housing, 9 positions, 1.25mm pitch, locking ramp, crimp termination, -40°C to 105°C.
