AS-Interface emergency stop enclosure for 22 mm command devices
The Siemens 3SF5811-0AE10 is an AS-Interface enclosure for a single 22 mm round command device, housing a red 40 mm emergency stop mushroom pushbutton with rotate-to-unlatch and a RONIS SB30 lock. It carries two NC contacts (1 NC + 1 NC) and terminates via an M12 connector on top, making it a self-contained safety input node on an AS-Interface bus. The yellow plastic top and included EMERGENCY STOP labels (separately enclosed in DE/EN) match the standard safety color coding for quick visual identification on the line.
Integration into an AS-Interface safety loop
The M12 connector on top simplifies field wiring — the enclosure connects directly to the AS-Interface flat cable via a standard M12 drop cable, eliminating the need for a separate junction box. The 22 mm round cutout accepts any compatible command device; here it ships pre-populated with the red 40 mm mushroom head and RONIS SB30 lock. The two NC contacts provide a dual-channel safety input, suitable for connecting to a safety monitor on the AS-Interface bus. The yellow enclosure top signals the safety function at a glance, which helps during panel audits and lockout/tagout procedures.
