Float-Mount SMT Socket for Automated Board-to-Board Alignment
The Molex 2121950012 is an 8mm SMT socket with a float-mount feature from the Coeur Sentrality 212195 series. It is a female receptacle (socket) terminal that uses crimp termination, designed to be soldered onto a PCB for a board-to-board interconnect. The float mount compensates for mechanical misalignment between mating boards during automated assembly, reducing stress on solder joints and improving yield in high-volume production.
Crimp Termination and Field-Serviceable Wire Attachment
Unlike pre-molded cable assemblies, this socket uses crimp termination, meaning the wire is attached via a separate crimp terminal that is then inserted into the housing. This allows the harness builder to select wire gauge and length per the application, and enables field replacement of individual contacts without replacing the entire cable assembly.
