Johnson Controls M9102-AGA-3S Actuator

The Johnson Controls M9102-AGA-3S is a non-spring return electric actuator engineered for precise floating control in commercial HVAC systems. Delivering 18 lb-in (2 Nm) torque, this direct-coupled actuator is ideal for positioning blades in VAV boxes, VVT two-position zone applications, and small-to-medium dampers. Operating on 24Vac, the unit features a synchronous drive that ensures a constant 30-second travel time (at 60 Hz) regardless of the load, providing the consistent performance required for tight building automation loops.

Designed for streamlined field installation, the M9102-AGA-3S utilizes M3 screw terminals for secure wiring, distinguishing it from the M9102-AGA-2S plenum cable alternative. Its compact NEMA 1 enclosure allows for mounting in tight-fitting locations, while the integrated manual gear release simplifies setup and manual positioning during commissioning. With a 100,000 cycle rating and a magnetic clutch to protect the gear train from stall-related damage, this Johnson Controls actuator provides the long-term reliability professional contractors demand.

• Consistent Timing: Synchronous motor provides a stable 30-second stroke (60 Hz) independent of load fluctuations.
• Contractor-Friendly Wiring: M3 screw terminals allow for direct, secure field connections without the need for additional junction boxes.
• High Durability: Rated for 100,000 full-stroke cycles and equipped with a magnetic clutch to prevent mechanical failure during stalls.
• Universal Mounting: Direct-shaft mounting with a single-screw coupler fits round shafts up to 1/2" or square shafts up to 3/8".
• Low Noise Operation: 35 dBA audible noise rating makes it suitable for open-ceiling environments and quiet office areas.

• Does this model include a timeout function? No, the M9102-AGA-3S is a floating control model without an internal timeout; ensure your VAV or VVT controller provides a signal timeout at the end of rotation to prevent excessive motor wear.
• Can I use this to replace an M9102-AGA-2S? Yes, this is the functional equivalent featuring screw terminals instead of a 48-inch plenum cable.
• What shafts are compatible with this actuator? It mounts directly to 3/8" to 1/2" (10 to 13 mm) diameter round shafts or 3/8" (10 mm) square shafts using the included single-screw coupler.
