Honeywell MN6120A1002 Actuator

The Honeywell MN6120A1002 is a heavy-duty Non-Spring Return Direct Coupled Actuator designed for precise floating control and on/off applications in commercial HVAC systems. Delivering a robust 175 lb-in torque, this motor is engineered to drive large dampers and valves with reliable performance. It operates on 24Vac power and features a self-centering shaft adapter, ensuring a secure fit on 3/8" to 1.06" round or 3/8" to 11/16" square shafts. The NEMA 2 rated housing protects internal components in demanding environments, while the manual declutch mechanism allows for manual positioning during commissioning or maintenance. With a 95-second nominal drive timing and a 95-degree rotational stroke, this actuator provides consistent airflow management. This unit serves as a high-performance direct replacement for MF41-6153, MF50-7173, and M9116-AGD-2, making it a versatile solution for retrofit projects and system upgrades requiring SPDT auxiliary switch capabilities.

• Universal Compatibility: Includes a self-centering shaft adapter and mounting bracket for quick installation on various damper shaft sizes.
• High Torque Output: Provides 175 lb-in (20 Nm) of torque to handle high-pressure commercial ductwork without stalling.
• Reliable Floating Control: Optimized for floating control signals, providing accurate positioning for VAV boxes and air handling units.
• Field Versatility: Features a manual declutch button for easy manual adjustment and troubleshooting without power.
• Environmental Resilience: Rated for ambient temperatures from -5 to 140 degrees Fahrenheit and up to 95% non-condensing humidity.

How do I wire the Honeywell MN6120A1002 for floating control?
This actuator uses a three-wire configuration for floating control. Ensure the 24Vac supply is consistent, and the controller provides the common signal to drive the motor clockwise or counter-clockwise as needed.

Can the MN6120A1002 replace older Johnson Controls M9116 models?
Yes, this unit is a direct replacement for M9116-AGD-2. The 175 lb-in torque rating and shaft adapter design provide a seamless transition for existing 24V applications.

Does this actuator have an internal return spring?
No, the MN6120A1002 is a non-spring return actuator. It will maintain its last position upon loss of power, making it suitable for applications where fail-safe positioning is handled by the control logic or is not required.
