The Siemens 3SF5813-3DE06 is an AS-Interface emergency stop enclosure with a metal housing, rated IP67 for washdown environments. It operates on a 26.5 to 31.5 V DC supply and includes three switching elements with positive opening contacts — meaning the NC contacts are mechanically forced open when the actuator is pressed, even if welded. The rotate-to-unlatch mechanism requires a deliberate twist to reset, preventing accidental restart.
What the ratings mean for fit
IP67 means the enclosure is dust-tight and protected against temporary immersion — suitable for food processing, washdown lines, or outdoor stations where hose-down cleaning is routine. The 22 mm mounting diameter and rectangular front (85 mm wide, 154 mm tall, 65 mm deep) fit standard panel cutouts. Pre-wired on strip terminal cuts installation time: no separate terminal block needed inside the enclosure. The three command points (actuator colors: red, black, black) give you one emergency stop plus two auxiliary pushbuttons in a single housing.
