About the 510210400 Pico-Blade Plug, 4-Pin 1.25mm
Molex 51021-0400 is a receptacle crimp housing from the PicoBlade 51021 series. It carries four circuits in a single row on a 1.25 mm (0.049 in) pitch and retains its mate with a friction lock, the housing moulded in natural-coloured polybutylene terephthalate. It is a free-hanging, in-line part rather than a board-mounted one: female socket contacts are crimped onto discrete wires and then inserted into the housing, and those contacts are ordered separately — Molex lists the PicoBlade 50058 and 50079 series socket contacts for this housing, which mates with PicoBlade headers and plug housings in the same family. Distributor data gives an operating temperature range of -40 °C to +105 °C. Published current and voltage ratings differ between catalogue sources for this housing, so the applicable rating should be taken from the Molex product specification for the contact and wire gauge actually used.

Typical applications
PicoBlade housings terminate the short, low-current wire runs inside compact electronics: UAV flight controllers and their peripherals, telemetry and GPS modules, camera and sensor boards, and general embedded instrumentation. The 1.25 mm pitch keeps a four-way connection narrow, which is why it is chosen where board and enclosure space is tight. Electronics and MRO benches stock the housings alongside the matching crimp sockets for cable assembly and repair work.
