The Volz Servos DA 20-T actuator is a compact brushless throttle actuator developed for integration in combustion engine systems. It has been fielded extensively by engine manufacturers for use in production engines. Featuring a brushless DC motor and contactless, wear-free position detection, the DA 20-T provides resistance to vibration and long-term operational stability. The actuator was validated through endurance testing, including a 1,000-hour vibration test and qualification to MIL-STD-810F and 810G standards.
The DA 20-T is designed for operation in elevated temperature environments, with all internal components specified for extended temperature ranges. Its shielded aviation-grade connection cable and robust aluminum construction ensure reliability in demanding airborne systems. The actuator contains no internal wiring and is optimized for minimal maintenance requirements across long service cycles.
