SQM50.361R1G7 Siemens Damper Motor

Overview

The Siemens SQM50.361R1G7 is a high-precision reversing actuator motor designed for the accurate positioning of dampers, flow control valves, butterfly valves, and other components requiring rotary motion. Part of the robust SQM5 series, this actuator is engineered for industrial and commercial burner applications, offering reliable performance in medium to large capacity oil and gas systems. It features a high degree of modulating accuracy and repeatability, making it an essential component for load-dependent control of combustion air and fuel volume.

Features

• Internal switches with six easily accessible and adjustable units for precise control
• Auto/manual selector switch and forward/reverse toggle for simplified field adjustments
• Externally visible shaft position indicator for quick status monitoring
• Low hysteresis gearing with a double-offset drive and potentiometer gearing for superior precision
• Field-reversible rotation allowing for either clockwise or counter-clockwise operation
• Durable construction with a wide range of field-exchangeable circuit boards and shafts to meet specific application needs
• UL and CSA approved for 110 Vac operation
