The Siemens 3RA9011-5AT20 is a kit for the FA. BESEL DMU 100T2. It is an accessory or replacement kit containing mounting hardware, bezel, or trim pieces to integrate the DMU 100T2 into a panel cutout. The DMU 100T2 is a display and operator unit from the Siemens FA (Factory Automation) family, used for local machine control and status indication. The 3RA9011-5AT20 kit provides the necessary parts to mount and seal the unit in a panel, so the buyer is sourcing a fitment solution, not a functional electronic module.
This part is in a current lifecycle stage.
What the Description Means for Fit
The description "Kit for FA. BESEL DMU 100T2" indicates this is the bezel or mounting kit specifically for the DMU 100T2 operator panel. The bezel provides the front seal (typically IP65 or better) and the mechanical interface between the panel cutout and the display unit. When specifying this kit, confirm the cutout dimensions match the DMU 100T2's mounting footprint — the kit itself does not include the display module. This kit provides the gasket, clamping frame, and fasteners to secure the DMU 100T2 from behind the panel.
