SQM50.461R1Z3R Siemens Damper Motor

Overview

The Siemens SQM50.461R1Z3R is a high-precision reversing actuator designed for the accurate positioning of air dampers, gas dampers, and flow control valves. Part of the robust SQM5 series, this motor-driven actuator is engineered for industrial and commercial burner applications that require a high degree of modulating accuracy and repeatability. It features a durable construction and is designed to provide reliable rotary motion for clockwise (CW) operation, making it a critical component in sophisticated combustion control systems.

Features

• High modulating accuracy and rotational resolution for precise damper control
• Internal switches including two limit switches and up to four auxiliary switches for versatile signaling
• Integrated auto/manual selector switch and manual forward/reverse toggle for easy maintenance and adjustment
• Externally visible position indicator for clear monitoring of the shaft’s orientation
• Low hysteresis design with double-offset drive and potentiometer gearing for stable performance
• Field-reversible clockwise or counter-clockwise operation capabilities
• Durable metal housing suitable for diverse mounting positions in industrial environments
