SQM50.484R1Z3 Siemens Damper Motor

Overview

The Siemens SQM50.484R1Z3 is a high-precision reversing actuator designed to provide accurate rotary motion for the positioning of air and gas dampers, flow control valves, and butterfly valves. Engineered for industrial and commercial burner applications, this electromotive actuator features a robust die-cast aluminum housing and a reversible synchronous motor. It is specifically designed for systems requiring a high degree of modulating accuracy and repeatability, offering a counter-clockwise (CCW) rotation and an integrated 3/8 inch square shaft for direct connection.

Features

• Reversible synchronous motor ensures precise control and locking-proof operation
• Counter-clockwise (CCW) rotation direction when facing the drive shaft
• Equipped with up to 8 switches, including 2 limit and 6 adjustable auxiliary switches
• Integrated dual-ended 3/8 inch square drive shaft for versatile mounting
• Disengagement clutches for both the drive shaft and camshaft allow for manual adjustment
• Externally visible position indicator for easy monitoring of shaft status
• Field-exchangeable circuit boards support multiple control signals and specialized functions
• Impact-proof and heat-resistant plastic covers for durability in demanding environments
