ATI Industrial Automation 9120-DC45-PLUG is a 4‑pole Teach Plug (TSI Teach Plug) designed for ATI tool changer systems. This plug provides the Teach Signal Interface connection used during tool teach and setup sequences, and it is documented as a spare part for ATI configurations such as the DL10 tool, as well as for the DJ6/M DJ2 family of master and tool modules. The 9120-DC45-Plug is commonly paired with the 9120-C-4EM-4EF TSI cable to establish the 4‑pin connection between the tool and controller, supporting the Teach plug pathway within ATI’s Quick-Change installation ecosystem.
