300 lb-in Direct Coupled Damper Actuators
Product Description
Direct Coupled SmartX Actuators are designed to be used in both
damper and valve control applications. The MS41-634x series actua-
tors are over the shaft non-spring return actuators compatible with
2…10 Vdc or 4…20 mA dc

control signals.
Features
• 300 lb-in (34 N-m) rated torque
• NEMA Type 4 housing (IEC IP56)
• Custom automatic current sensing motor control provides extended reliability
and repeatable timing
• Direct coupled to the damper shaft with dual industrial hardened universal
mounting clamps
• Integral wiring for proportional control by 2…10 Vdc or 4…20 mA dc
1
• Clockwise or counterclockwise rotation is determined by actuator mounting
position
• Manual override for ease of installation and manual operation of damper
• Accurate 92° travel digitally controlled
• Integral position indication scale
• Rugged die-cast housing
• Oil immersed gear train provides continuous lubrication
• Rated for operating temperatures up to 140 °F (60 °C)
• Five year warranty
• MS41-634x SmartX Actuators can be double mounted (gang mounting) to
accommodate high torque application requirements (2 to 4 actuators)
• Position feedback signal
