10–30 V, 20 mm brushless throttle actuator with sealed aluminum housing & contactless detection

The DA 20-T actuator from Volz Servos is a compact brushless throttle actuator designed for integration into combustion engine systems used in UAV and defense platforms. Fielded across a variety of production engines, it provides stable and precise throttle control through a brushless DC motor and a contactless position detection system that eliminates wear and enhances vibration resistance. The actuator’s durability and performance have been verified through endurance evaluations, including a 1,000-hour vibration test and qualification to MIL-STD-810F and 810G standards.

Built for operation in elevated temperature environments, the DA 20-T incorporates internal components rated for extended temperature ranges. Its robust, HART-coated aluminum enclosure and shielded aviation-grade connection cable deliver protection against environmental stress and electromagnetic exposure. With no internal wiring and minimal maintenance requirements, the DA 20-T actuator provides reliable, long-term operation across military propulsion and control systems that demand continuous stability and resistance to mechanical and thermal fatigue.
