SQM10.17502 Siemens Actuator

Overview

The Siemens SQM10.17502 is a high-precision, reversible motor actuator designed for the accurate positioning of air dampers and control valves in industrial and commercial burner systems. Engineered for reliability and energy efficiency, this synchronous motor-driven actuator ensures optimal combustion by maintaining precise fuel-to-air ratios. It features a robust die-cast aluminum housing and self-lubricating bearings, making it suitable for demanding environments such as heat treatment plants and HVAC systems where continuous or high-demand performance is required.

Features

• Reversible, locking-proof synchronous motor ensures consistent drive speed and torque
• Integrated cam stack with 5 adjustable auxiliary switches for flexible control sequencing
• Manual cam adjustment using an enclosed hook spanner or standard tool
• Internal scale for precise switching point position monitoring
• Maintenance-free reduction gearing with self-lubricating sinter-bronze bearings
• Durable die-cast aluminum housing with a dark-grey plastic cover for industrial protection
• Counterclockwise direction of rotation when facing the drive shaft
