What It Fits
The LA9AADIS7: This adapter is designed for the TeSys D and TeSys F contactor families — the ones you see in motor starter assemblies across pump panels, conveyor controls, and compressor cabinets. It mounts between the contactor body and the auxiliary contact block, extending the mechanical stack so the add-on block sits flush and locks in place. No tools needed; it's a snap-on fit. Because it's a passive mechanical part, there's no electrical rating to worry about. The only spec that matters is the mechanical fit with your contactor model — if you're using a TeSys D or F, this adapter is the correct interface.
