M9108-AGx-2 Series On/Off and Floating Electric
Non-spring Return Actuators
The M9108-AGx-2 Series direct-mount electric
actuators operate on 24 VAC or VDC power, and are
available for use with on/off and floating controllers.
These bidirectional actuators do not require a damper
linkage, and are easily installed on a damper with a
round shaft up to 3/4 in. (19 mm) in diameter or a
square shaft up to 5/8 in. (16 mm). Actuators may be
direct- or remote-mounted to a damper.
A single M9108-AGx-2 model delivers up to 70 lb·in
(8 N∙m) of torque. The angle of rotation is
mechanically adjustable from 0 to 90° in 5-degree
increments. Integral auxiliary switches are available to
indicate end-stop position or to perform switching
functions at any angle within the selected rotation
range. Position feedback is available through either a
135 or 1,000 ohm potentiometer.

Features and Benefits
Two Control Inputs Meet the needs of most applications
Output Position Feedback Provides simple, closed-loop control with accurate
position sensing
Electronic Stall Detection Ensures higher reliability by deactivating the
actuator motor if a stall condition is detected
Dual Scale (0 to 90° and Indicates the position of the actuator’s rotation in
90 to 0°) on the Cover 10° increments
Removable Coupler Allows adjustment of the rotation range from
0 to 90°
Steel U-bolt Clamp Provides four-point damper shaft gripping
Coupled to a Ball-style Regulates the flow of hot or chilled water,
Valve with Linkage 50% glycol solution, and low pressure steam
Manual Gear Release Simplifies installation, setup, and field adjustments
National Pipe Thread (NPT) Provides easy connection for electrical fittings
Threaded Housing
