SQM10.16562 Siemens Actuator

Overview

The Siemens SQM10.16562 is a reversible electromotoric actuator designed for the precise control of air dampers and control valves in oil and gas burners. This robust servo motor ensures optimal combustion by maintaining the correct fuel-to-air ratio, enhancing energy efficiency and operational safety in industrial heating systems. It features a locking-proof synchronous motor and a durable die-cast aluminum housing, making it a reliable component for continuous or intermittent burner operations.

Features

• Reversible synchronous motor with adjustable cams for precise positioning
• Integrated cam stack actuates end and auxiliary switches to signal position or control secondary devices
• Self-lubricating sinter-bronze bearings in the reduction gearing ensure maintenance-free operation
• Disengageable gear train allows for manual adjustment of the drive shaft during installation
• Durable construction with a die-cast aluminum gear housing and an impact-resistant plastic cover
• Internal scale for easy setting of switching points and angular positions
