What This Connector Is
The Molex 2045320901 is a 9-circuit receptacle housing from the Micro-Lock PLUS 204532 series. It is the female socket half of a wire-to-board interconnect system, designed for free-hanging (in-line) mounting with crimp termination. The housing accepts separately ordered female crimp terminals, which are inserted into the 1.25 mm pitch cavities and retained by the primary latch.
Where It Fits: Applications and Environment
This receptacle is suited for wire-to-board power and signal interconnects in space-constrained consumer, automotive, and industrial applications. The 1.25 mm pitch keeps the board footprint small, while the latch holder prevents accidental disconnection under vibration — useful in appliance control boards, LED lighting modules, and infotainment harnesses.
Mating and Termination
The 2045320901 mates with Micro-Lock PLUS 1.25 mm pitch headers (male pin headers) of the same series and position count. Termination is crimp-style: the installer selects the correct Molex crimp terminal for the wire gauge, crimps it onto the stripped wire, and inserts it into the housing cavity until the latch clicks. Contacts are NOT included with this housing — order the appropriate female crimp terminals separately. The latch holder on the housing engages with the header's locking ramp for a positive retention that resists vibration and cable pull.
