About the Molex 51021-0200 2-Pin Plug, 1.25 mm Pitch
The Molex 51021-0200 Connector Plug 2-Pin Female Crimp is a 2-circuit, single-row receptacle housing from the Molex PicoBlade 51021 series, a 1.25 mm-pitch wire-to-board and wire-to-wire interconnect system. The housing accepts Molex PicoBlade female crimp socket contacts (50058 and 50079 series) terminated to 26–32 AWG discrete wire, and retains the mated header by friction lock. Molex rates the PicoBlade system at up to 1.0 A per circuit, with an operating temperature range of -40 °C to +105 °C, and positions the 1.25 mm pitch as a space saving of roughly 45 % of PCB area against typical 2.00 mm wire-to-board systems. This part is supplied in the natural (unpigmented) colour for free-hanging cable-end use. Crimp contacts are ordered separately and are not included with the housing.

Typical applications
Two-circuit PicoBlade housings of this type are used for compact power-pair and single-signal cable assemblies in space-constrained electronics — for example battery leads, fan leads and sensor tails inside small enclosures. The 1.25 mm pitch suits dense boards where a 2.00 mm connector would not fit.
