Siemens 3SU1000-4WS10-0AA0 RFID Actuator Plastic Black 4 Position

Siemens 3SU1000-4WS10-0AA0 RFID Actuator is a 22 mm round, plastic black RFID actuator for the Sirius ACT ID key-operated switch family, delivering four switch positions (O, I, II, III) with a 3×45° operating angle. This 0AA0 variant is supplied without an ID key, and key removal is possible in all four positions. The actuating element has a 29.5 mm outer diameter, and the unit is designed for use in industrial control systems where a physical key governs the switch state and RFID provides traceability. This actuator supports four-position switching within 22 mm Sirius ACT installations for applications such as start/stop or mode selection, combining key-based access with RFID identification to secure critical control points.
