3.4 mm SMT Socket — Coeur Sentrality 212194 Series
The Molex 2121940018 is a 3.4 mm SMT standard socket from the Coeur Sentrality 212194 series. This is the SMT receptacle half of a wire-to-board interconnect system — it sits on the PCB and accepts the mating crimp terminal plug.
This socket mates with the 212195 series crimp terminal housings — specifically the 2121950012, 2121955010, and 2121955018 variants. Those are the plug-side members that accept the wire crimp terminals and lock into this SMT socket. The 212195 series is also active, so both halves are equally available for a production BOM.
Packaging and Sourcing
Supplied in Cut Tape (CT) and Bulk packaging — the CT option suits prototype or low-volume builds where full reel quantities aren't needed.
