LKS210-10 | Honeywell AC Damper/Flap Servo Actuator 0-90° Stroke, 200-240 V

Honeywell · Motors & Motion

Description  The Honeywell LKS210-10 is a servo-motor/damper actuator designed for burner and combustion applications where a reliable 200-240 V AC actuator provides precise 90° flap or damper positioning. With its worm-gear self-locking mechanism and rapid 5-second 90° stroke time, it ensures accurate control of air or fuel flows.     Technical Specifications  Condition New/Never Used Surplus Brand Honeywell Category Actuator / Motion Control Part Number LKS210-10 Subcategory Servo Motor / Damper Actuator Voltage 200-240 V AC, 50/60 Hz Duty Cycle Approx. 70% ED Stroke Angle 0° to 90° Stroke Time ~5 seconds for 90° stroke Torque Output Approx. 1.5 Nm Drive Shaft Square socket ~8×8 mm or Ø10 mm, shaft depth 25 mm Gear Mechanism Worm gear with self-locking function Housing Material Synthetic, self-extinguishing material Protection Rating IP44 (standard variant) Ambient Temperature Range –10 °C to +60 °C Mounting Flange mounting (three M5 screws typical) Weight Approx. 1 kg Country of Manufacture Hungary (for some lots)     Information About LKS210-10 The LKS210-10 is part of Honeywell’s LKS210 series of modulating actuators, primarily used in oil or diesel burner systems and industrial combustion setups. Typical specification notes indicate operation at 200-240 V AC, 50/60 Hz, with a duty cycle of 70% ED. It features a synthetic, self-extinguishing housing, worm gear drive with self-locking function (for secure flap positioning when power is off), and drive output shaft compatible with standard flame-train or damper linkages. This actuator is frequently found in retrofit installations for burner manufacturers such as Riello and other European burner OEMs. Key Features: 200-240 V AC Operation (50/60 Hz): Suits standard burner control voltage ranges. 90° Stroke Angle in ~5 Seconds: Rapid actuator speed for improved system response. Self-Locking Worm Gear: Maintains flap position after power is removed, enhancing safety and reliability. High Torque Output: Typical torque around 1.5 Nm for damper/flap control in combustion systems. Synthetic, Self-Extinguishing Housing: Designed for safety in industrial heat/ combustion environments. Direct Shaft Coupling: Square socket (≈ 8×8 mm) or Ø10 mm shaft depth 25 mm for direct linkage connection. IP44 Protection Rating (depending on variant): Suitable for indoor burner room or industrial environment use. Maintenance-Free Design: Long service life with minimal upkeep required. Wide Ambient Temperature Range: Typical range –10 °C to +60 °C (operational environment). European OEM Compatibility: Frequently used as original or replacement actuator in burner assemblies and damper systems. The LKS210-10 delivers the reliability and precision required for modulating burner or damper control in industrial and commercial combustion systems.
