SQM50.460R1Z3 Siemens Damper Motor

Overview

The Siemens SQM50.460R1Z3 is a high-precision reversing actuator designed for the accurate positioning of air dampers, gas dampers, and flow control valves in medium to large capacity oil and gas burners. As part of the SQM5 series, this motorized actuator is engineered for industrial and commercial applications that require a high degree of modulating accuracy and repeatability. It features a robust design with die-cast aluminum housing and a synchronous motor, ensuring reliable performance in demanding burner control environments.

Features

• Multiple control input options including 4-20 mA, 0-135 Ohms, 0-10 Vdc, and 0-20 mA for versatile system integration
• Equipped with two limit switches and up to four internal auxiliary switches for flexible position feedback
• Integrated auto/manual selector switch and a manual forward/reverse toggle switch for simplified commissioning and maintenance
• Disengagement clutches for the drive shaft and cam drum allow for quick manual alignment
• Externally visible position indicator provides immediate visual confirmation of the shaft angle
• Field reversible rotation allows for both clockwise and counter-clockwise operation to suit specific installation needs
• Durable construction with impact-proof and heat-resistant plastic covers and a die-cast aluminum gear housing
