The Siemens SQM10.16562 is a robust electromotoric actuator (servomotor) designed for the precise positioning of gas and air dampers on medium to large industrial burners. It is part of the SQM10 series, which is distinguished from the compact SQN series by its heavy-duty die-cast aluminum housing and high-torque gearing, making it suitable for demanding combustion applications in industrial kilns, marine boilers, and large process heaters.
The actuator operates on 220–240 V AC and provides a nominal torque of 10 Nm, with a counterclockwise (CCW) rotation direction when facing the drive shaft. It uses a reversible synchronous motor and a traditional cam-and-switch mechanism for reliable position feedback and limit switching, integrating seamlessly with burner management systems (BMS) such as the Siemens LMV series.

Important Compatibility Note: When replacing an existing SQM10 actuator, verify the rotation direction (CCW vs. CW), running time (29s vs. 14s), and potentiometer resistance (if fitted) match the original unit. A mismatched running time can destabilize the burner's PID control loop .

Q1: What is the Siemens SQM10.16562?
It is a reversible electromotoric actuator for positioning gas and air dampers on medium to large industrial burners. It provides 10 Nm nominal torque, counterclockwise rotation, and 29-second running time for 90° at 50 Hz .
Q2: What is the difference between SQM10 and SQM11?
The SQM10 (this item) rotates counterclockwise (CCW) when facing the drive shaft. The SQM11 rotates clockwise (CW). Both share identical mounting footprints and electrical ratings .
Q3: What is the operating voltage?
The actuator operates on AC 220–240 V, 50/60 Hz, with a power consumption of 9 VA .
Q4: How many auxiliary switches does it have?
It has 5 auxiliary changeover (SPDT) switches plus 2 limit switches, rated at 10 (3) A, 24–250 V AC .
Q5: What is the rotation angle?
The adjustable rotation range is up to 160°, set via internal cams .
Q6: Can I add a feedback potentiometer?
Yes. The housing accommodates optional ASZ series potentiometers for position feedback (typically 0–1000 Ω or 4–20 mA converted). This allows the burner controller to monitor actual damper position .
Q7: What is the running time for 90°?
The running time for a 90° stroke is 29 seconds at 50 Hz (approximately 24 seconds at 60 Hz) .
Q8: What is the shaft diameter?
The standard drive shaft is 10 mm in diameter .
Q9: What is the protection class and ambient temperature range?
The actuator is IP54 rated and operates from -20°C to +60°C .
Q10: What is the country of origin?
Germany .
Q11: What should I verify before ordering?
Always verify the exact model number (SQM10.16562 vs. SQM11 for CW rotation), confirm the running time (29s vs. 14s) matches your burner control requirements, check whether a potentiometer is needed for feedback, and ensure the rotation direction is compatible with your damper linkage.
