Honeywell M4185B1058 Motor 2 Position/Reset 1 Auxiliary Switch 24V/120V/230V

The Honeywell M4185B1058 is a two-position, spring-return motor designed for use in HVAC systems. It operates on a variety of voltages (24V, 120V, or 230V) and delivers 60 lb-in of torque to rotate a damper or valve. When power is applied, the motor drives the shaft in one direction until it reaches its endpoint. Once power is removed, a spring returns the shaft to its original position. This spring-return feature ensures the damper or valve closes automatically in case of a power outage, potentially preventing unwanted heating or cooling. The M4185B1058 also includes an adjustable stroke from 90 to 160 degrees, allowing for customization depending on the specific application. Additionally, it boasts a built-in auxiliary switch that can be used to signal other equipment based on the motor's position. This motor is commonly found in 1heating, ventilation, and air conditioning systems, typically controlling dampers that regulate airflow throughout a building. By precisely positioning dampers, the M4185B1058 helps maintain consistent temperature and optimize comfort levels. It also contributes to energy efficiency by ensuring proper airflow and reducing unnecessary heating or cooling cycles.
