The DA 15-N brushless actuator from Volz was recently tested during a high-altitude mission reaching approximately 110,000 feet (33,000 meters) near the edge of space.
Exposed to extremely low temperatures and very low atmospheric pressure, the compact actuator endured conditions that challenge many conventional electronic systems, demonstrating its ability to withstand a demanding operating environment.
As the smallest and lightest full brushless actuator in the company’s portfolio, the DA 15-N is designed for harsh environments and safety-critical applications. Operating from 5–30 V, it combines a brushless DC motor with a contactless position sensing system to deliver long service life, resistance to vibration and shock loads, and minimal susceptibility to electromagnetic interference. The actuator also provides standard position, temperature, and current feedback, with fully programmable functionality for application-specific requirements.
Featuring a lightweight aluminum housing with IP67-rated protection and resistance to saltwater exposure, the DA 15-N is suited to applications requiring compact, durable actuation in challenging environments. Optional features include an ISS gear protection system, extended travel angles of up to 330 degrees, RS-485 and CAN communication protocols, and customized housing configurations.
