SQM10.16561 Siemens Actuator

Overview

The Siemens SQM10.16561 is a reversible electromotoric actuator designed for the precise control of air dampers and gas or oil burner control valves. Engineered for industrial and commercial burner applications, this high-torque servo motor ensures optimal combustion by maintaining an accurate fuel-to-air ratio. It is a critical safety and efficiency component used in conjunction with burner controls or switching devices equipped with changeover contacts.

Features

• Reversible synchronous motor with locking-proof design for reliable operation
• Adjustable cam stack for precise setting of switching points and angular positions
• Built-in scale at the beginning of the cam stack for easy internal adjustments
• Integrated gearing can be decoupled via a lever for manual adjustment of the drive spindle
• Maintenance-free reduction gearing with self-lubricating sinter-bronze bearings
• Durable die-cast aluminum gear housing with an impact-proof plastic cover
• Internal auxiliary switches for additional control and signaling functions
