As with the Micro‑DC(MDC) and Micro‑AC(MAC) series, the Euro‑AC (MEC) series connectors do not imply that they are only used in AC applications. MEC series uses the M12 mating thread like the MDC series, and they are also commonly used for coding purposes in conjunction with the MDC series. Made popular by the European market it has found its way into many industrial applications as well as some bus systems. The MEC series has a reversed single keyway known as B‑Code. Using an MEC alongside other M12 threaded receptacles on the same panel will eliminate the possibilities of plugging the wrong cable into the wrong receptacle, safely coding your connection without adding cost.
