Honeywell M8405A1006 SR Motor

The Honeywell M8405A1006 is a professional-grade spring return damper actuator engineered for precise airflow management in commercial and residential economizer systems. Operating on a 24V AC power supply, this synchronous motor provides reliable three-position control, ensuring efficient ventilation and combustion air regulation. With a 25 lb-in torque rating and a 90-second timing at 60 Hz, the unit facilitates a full 90-degree stroke with a counterclockwise (CCW) rotation. Designed to be a direct replacement for ME-12313, the M8405A1006 features a rugged, glass-fiber reinforced plastic housing that is both corrosion-resistant and lightweight. The internal spring return mechanism is a critical safety feature, automatically returning the motor shaft to the normal position during power loss. Field-proven for integration with building automation systems, it utilizes 1/4-inch quick-connect terminals for streamlined wiring and includes a single-ended drive shaft with a crank arm assembly for immediate installation in HVACR economizer applications.

• Fail-Safe Operation: Integrated mechanical spring return ensures dampers close or open to a safe position during power interruptions.
• Precise Positioning: Supports three-position control and floating point signals for accurate environmental adjustments.
• High-Torque Performance: Delivers 25 lb-in of consistent torque, suitable for driving medium-sized dampers in ventilation and exhaust systems.
• Direct Retrofit Compatibility: Specifically designed to replace legacy ME-12313 actuators, minimizing downtime during field service.
• Industrial Build Quality: High-impact reinforced plastic case maintains structural integrity in ambient temperatures ranging from -25°F to 125°F.

Can I use the M8405A1006 to replace an older ME-12313 motor?
Yes, this model is the designated high-efficiency replacement for the ME-12313. It maintains compatible mounting footprints and electrical requirements for seamless retrofitting.

Does this actuator require a specific linkage for installation?
The unit includes a crank arm; however, for many standard economizer damper applications, it is designed to work with the Q298B linkage system.

Is the rotation direction adjustable in the field?
The M8405A1006 is fixed for counterclockwise (CCW) rotation from the shaft end of the motor, which is the standard configuration for most compatible HVAC systems.
