The Molex 5056061001 is a 10-circuit plug housing from the CP-3.3 505606 series, a 3.30 mm pitch wire-to-wire interconnect family. It is the free-hanging (in-line) half of a two-piece connector system — the receptacle mates with a matching header.
You need to source the male pin crimp terminals separately — the CP-3.3 series uses a specific terminal (often Molex 505606-... or equivalent) that matches the 3.30 mm pitch and the housing cavity. Buying the housing alone and forgetting the terminals is the single most common BOM miss on this part.
This plug housing accepts male pin contacts via crimp termination. The mating half is a CP-3.3 receptacle header with the same 3.30 mm pitch and 10 circuits — look for the 505606 series receptacle housings. The latch lock engages audibly when fully mated; no secondary lock is listed, so verify terminal retention by feel during assembly.
