Honeywell M8405A1006 3Pos 90Deg90Sec 24V Sr Motor

The Honeywell M8405A1006 emerges as a 25 lb-in spring return damper actuator, engineered for precise control within HVAC systems. Powered by a synchronous motor, it interprets control signals (0-10 VDC, 2-10 VDC, or 4-20 mA) into specific shaft rotations, enabling versatile control modes for dampers, including two-position, three-position, floating, or modulating. Particularly useful for economizer, ventilation, and combustion air dampers in residential and commercial setups, it ensures system integrity during power failures by spring-returning the damper to its normal position. Compact in size, it suits space-constrained applications, and its high-impact, glass-fiber reinforced plastic case ensures durability and corrosion resistance. Operating quietly to minimize noise disruption, its quick-connect terminals facilitate easy installation, and an adjustable mid-position allows for fine-tuning damper control.
