SQM50.464R1G7R Siemens Damper Motor

Overview

The Siemens SQM50.464R1G7R is a high-precision, reversing electromotive actuator designed to position flow control valves, butterfly valves, and dampers in industrial burner and HVAC applications. Engineered for accuracy and repeatability, this motor is particularly well-suited for modulating control systems. It features a robust design capable of clockwise rotation and includes a double potentiometer for precise position feedback, making it an essential component for high-demand combustion systems like the Siemens LMV5.

Features

• Reversing electromotive motor with clockwise (CW) rotation
• Equipped with a double potentiometer for accurate position feedback
• Integrated internal circuit board for 4-20 mA input signal processing
• Up to six easily adjustable internal micro-switches for end-position and auxiliary signaling
• Durable, maintenance-free gear train and bearings for long-term reliability
• Field-reversible and adaptable mounting positions for installation flexibility
• Disengageable drive shaft and camshaft for manual adjustment or maintenance
