Siemens SQM50.260R1G4 Damp Motor

Siemens SQM50.260R1G4 Damp Motor is a shaftless damper actuator designed for HVAC damper control. This no-shaft variant operates on 110 V and is specified with a 90# torque rating and 6SW wiring, making it suitable for inline damper applications where a compact, direct-drive solution is required. Part of the SQM50 damper motor family, the SQM50.260R1G4 positions dampers within ductwork to regulate airflow in commercial and industrial HVAC installations. The 260R1G4 suffix identifies this exact configuration within Siemens' line, ensuring compatibility with damper assemblies and control interfaces used in building automation. The shaftless design enables installation in tight spaces where a traditional actuator shaft would be impractical, while maintaining a compact mounting footprint suitable for standard damper mounting patterns. Designed for integration with typical HVAC control schemes, these actuators translate electrical input into damper movement to regulate airflow and help achieve energy efficiency in controlled environments. Compatibility with common damper mounting patterns and control interfaces is supported by this variant.
