Siemens 6AV3688-3XY38-3AX0 SIMATIC KP8 Design Blank Front IP65 5-Slot HMI Extension Unit

The Siemens 6AV3688-3XY38-3AX0 is a SIMATIC KP8 design empty front panel for building modular operator stations: an aluminum blank front with five slots for standard 22.5 mm command and signaling devices, such as pushbuttons or an emergency-stop button. It mounts into the Extension Unit of any 15-inch or 19-inch 4:3 PRO panel, rated IP65 at the front and IP20 at the rear.

Selection Notes

The five 22.5 mm slots let a panel builder add pushbuttons, selector switches, or an emergency-stop button directly next to the HMI instead of drilling a separate enclosure cutout, and the front is also rated suitable for safety functions. It only fits the Extension Unit of 15-inch and 19-inch 4:3 PRO devices, so confirm the panel size and format before ordering. IP65 at the front protects the mounted command devices against washdown, while the IP20 rear still needs a closed cabinet behind it.

Applications

Fits modular operator stations where a 15-inch or 19-inch 4:3 PRO HMI needs hardwired controls, such as an e-stop or mode-select switch, mounted directly beside the display in the same bezel.
