Product Description P/N: M740A1038
Description
The Honeywell M740A1038 is a high-torque “Actionator” motor/actuator rated for 120 V AC at 60 Hz (40 VA) with a 60-second full-stroke time. Designed for direct-coupled damper or valve applications, it provides reliable rotary motion in industrial HVAC and control systems. This unit is discontinued by the manufacturer, making it a specialist choice for legacy equipment replacement.

Information About M740A1038
The M740A1038 belongs to Honeywell’s M740A series of “Actionator” motors/actuators, intended for positioning dampers, butterfly valves, slip-stem valves and other mechanical control elements. The series features die-cast aluminum enclosures, sealed shafts (Buna-N O-rings), internal disc brakes to hold position when power is removed, and adjustable crank-arms for linkage connection. Within the M740A family, the “1038” variant is specified for 120 V AC applications with a timing of approximately 60 seconds per 180° rotation (standard model timing), and no auxiliary switches or slide-wire feedback by default. The unit is designed for demanding industrial installations where long-life, stable positioning and rugged construction are required.
Key Features:
- 120 V AC Power Supply: Compatible with standard single-phase control circuits.
- 60-Second Full-Stroke Time: Provides smooth 180° rotation in one minute for controlled movement.
- Internal Holding Brake: Maintains shaft position when power is removed for safety and precision.
- Heavy-Duty Worm Gear Mechanism: Ensures long-life and high torque for demanding applications.
- Rugged Aluminum Housing: Provides protection and durability in industrial environments.
- Oil-Resistant Shaft Seals: Buna-N O-rings prevent contamination and wear.
- Adjustable Crank Arm: Allows customized linkage setups for valves and dampers.
- High Torque Output: Designed to drive large or high-friction control components.
- Easy Field Installation: Suitable for direct coupling or linkage mounting.
- Legacy Model Support: Compatible with existing Honeywell control systems still in service.
The M740A1038 delivers the power, precision, and reliability required for industrial automation and HVAC control applications.
