SQM50.364R1Z3R Siemens Damper Motor

Overview

The Siemens SQM50.364R1Z3R is a high-precision reversing actuator designed for the accurate positioning of air dampers, flow control valves, and butterfly valves in industrial and commercial burner applications. This model is engineered for reliability and repeatability, featuring a robust die-cast aluminum housing and impact-proof plastic covers. It belongs to the SQM5 series, which is known for its modular design and ability to accommodate various exchangeable circuit boards and potentiometers to meet specific control requirements.

Features

• Reversing motor with field-reversible clockwise or counterclockwise operation
• Six internal, easily adjustable auxiliary switches for flexible position feedback
• Integrated auto/manual selector switch and manual forward/reverse toggle switch for easy commissioning
• Drive shaft and camshaft can be independently disengaged from the gear train
• Externally visible position indicator for quick status verification
• Modular design allows for field-exchangeable circuit boards, potentiometers, and shafts
• Low hysteresis gear train with double-offset drive for high resolution and accuracy
