The Molex 0510050300 is a 3-circuit receptacle housing from the 51005 series, a 2.00 mm pitch wire-to-wire or wire-to-board interconnect family. It is a single-row, free-hanging (in-line) housing that accepts female socket crimp terminals — the contacts are ordered separately and are not included with this part. The natural colour housing is the standard unkeyed version, intended for general-purpose internal wiring where a compact, low-profile connector is needed.
Mating and termination
This receptacle mates with the matching 51005 series 3-circuit male header (order the header separately). The crimp termination requires a separate female socket terminal — the 51005 series crimp contact — which must be ordered as a line item. The 2.00 mm pitch and single-row layout keep the mated pair compact, suited for low-current signal or power distribution inside an enclosure where space is tight.
