SQM50.480R1Z3 Siemens Damper Motor

Overview

The Siemens SQM50.480R1Z3 is a high-precision reversing actuator designed for the accurate positioning of air and gas dampers, flow control valves, and butterfly valves in industrial burner applications. This electromotive actuator is engineered for systems requiring a high degree of modulating accuracy and repeatability. Built with a robust aluminum housing, it is designed for durability and long-term service in demanding combustion environments. This specific model is supplied without a drive shaft, allowing for flexible configuration based on the specific mechanical requirements of the system.

Features

• High-torque performance for large dampers and flow control valves
• Reversing motor allows for clockwise and counterclockwise rotation
• Integrated electronic modules support multiple control inputs including 4 to 20 mA, 0 to 10 Vdc, and 0 to 135 Ohm
• Equipped with 8 internal, easily adjustable auxiliary switches (2 end limits and 6 auxiliary)
• Self-disengaging drive shaft and camshaft for simplified maintenance and setup
• Internal and external position indication for real-time monitoring
• Durable aluminum housing with corrosion resistance for industrial longevity
