SQM50.467R1Z3R Siemens Damper Motor

Overview

The Siemens SQM50.467R1Z3R is a high-precision, reversing electromotive actuator designed to drive air and gas dampers in medium to large capacity oil and gas burners. Engineered for load-dependent control of gas, oil, and combustion air, this motor is specifically built for applications requiring high modulating accuracy and repeatability. It features a robust die-cast aluminum housing with impact-proof plastic covers and is designed for clockwise (CW) rotation.

Features

• High-torque performance providing 140 in-lbs for reliable damper control
• Multi-input compatibility accommodating 4 to 20 mA, 0 to 135 Ohms, and 0 to 10 Vdc signals
• Integrated auto/manual selector switch and manual forward/reverse toggle for easy adjustment
• Self-checking mechanism with two limit switches and up to four internal auxiliary switches
• Disengagement clutches for separate adjustment of the drive shaft and cam shaft
• Durable construction with maintenance-free gearwheels and bearings for an estimated 10-year service life
