The Molex 2147192120 is the 12-circuit header housing from the Zero-Hachi 214719 series, a fine-pitch wire-to-board interconnect family. It accepts non-gendered crimp contacts and terminates to discrete wires for a free-hanging (in-line) connection to a mating header on the PCB.
Contacts Are Ordered Separately — Here's What to Know
This housing ships empty — the listing note is explicit: Contacts Not Included. The terminal part number is not listed in this record, so confirm the correct contact with the mating header's datasheet or the series application note. The crimp termination suits automated or manual harness assembly; the free-hanging mount means the housing floats in the harness, not on the board.
The 0.80 mm pitch is tighter than the 2.54 mm or 2.00 mm found on standard wire-to-board connectors, so the board layout and the crimp terminal size are both constrained by this fine spacing. The single-row arrangement keeps the harness narrow, which helps in cable-routing-dense enclosures.
