SQM53.464R1Z3R Siemens Damper Motor

Overview

The Siemens SQM53.464R1Z3R is a high-precision reversing actuator designed for the accurate positioning of air dampers and flow control valves in industrial and commercial burner systems. Engineered for reliability and flexibility, this electromotive motor provides 200 in-lbs of torque and is capable of multi-input signal regulation. Its robust design allows for clockwise (CW) rotation and features a 3/8 inch square shaft, making it suitable for high-demand applications that require consistent modulating accuracy and repeatability.

Features

• Reversing actuator with internal and external position indication
• Integrated electronic module for multi-signal input compatibility
• Field-reversible operation, though this specific model is configured for clockwise rotation
• Disengagement clutches for the drive shaft and cam drum to allow for manual adjustment
• Maintenance-free gearwheels and bearings for long-term service life
• Impact-proof and heat-resistant plastic covers with a die-cast aluminum housing
• Adjustable input signal override and selectable electronic linearization
• Equipped with two limit switches and up to four internal auxiliary switches
