It carries both EMERGENCY OFF and EMERGENCY STOP functions, with a rotate-to-unlatch mechanism that requires a deliberate twist to reset after activation — no accidental re-energisation. Six command points are arranged on the rectangular front: illuminated pushbuttons, a knob, a standard pushbutton, an emergency-stop mushroom pushbutton, and a dummy plug. The front ring is silver metal; the enclosure top is grey. Eight switching elements handle the safety circuit logic, and the unit is pre-wired on a strip terminal for quick panel connection. Rated supply is 26.5... 31.5 V DC, which matches the standard AS-Interface bus voltage range. The integrated LED light source runs on AC/DC and is socketed for replacement. Vibration resistance per IEC 60068-2-6 covers 20... 200 Hz at 5g. The enclosure mounts vertically and uses a 22 mm mounting diameter for the actuator elements. Dimensions are 85 mm wide, 65 mm deep, and 280 mm tall — sized for a standard AS-Interface drop station on a machine frame or enclosure door. Floor mounting is the intended installation method.","metaTitle":"Siemens 3SF5816-2DA00 AS-Interface Emergency Stop, IP67, 6-c","metaDescription":"Siemens 3SF5816-2DA00 AS-Interface emergency stop station with 6 command points, IP67, 26.5...31.5 V DC.
