The Siemens 3SF5812-2DB00 is an AS-Interface enclosure with two pushbutton command points, designed as an A/B slave with 4 inputs and 3 outputs. It's built for floor mounting in a metal housing rated IP67, so it holds up in washdown or dusty environments on a production line. The pushbutton actuators are plastic with a black/white color scheme; the front ring is metal with a silver finish. No emergency stop or emergency off function here — this is a general-purpose command station, not a safety-rated device.
IP67 means the enclosure and optics survive hose-down cleaning and dust ingress — suitable for food-and-bev lines or outdoor conveyor stations where you need a pushbutton that won't die from a pressure wash. The 22 mm mounting diameter and round installation opening match standard panel cutouts; the rectangular front shape and vertical mounting orientation dictate how it sits on a machine frame or floor stand. Depth is 65 mm, width 85 mm, height 114 mm — check your enclosure clearance before committing. Rated DC voltage at 30 V on the switching elements; the two switching elements lack positive opening (no forced break), so this isn't a safety interlock — it's a standard control pushbutton station for AS-i bus communication.
