Woking, UK - 27, May 2026 - TT Electronics, a global provider of mission-critical power and sensing technology, has been selected to supply Hallogic® Hall-effect sensors for integration into fan assemblies on NASA’s Dragonfly rotorcraft mission. The sensors support a spacecraft subsystem where reliability and consistency are essential across the programme lifecycle.
Hallogic® Hall-effect devices, part of the Optek technology portfolio, are designed for non-contact motion sensing and switching, with variants processed and screened for military and space-grade applications where consistency and reliability are design priorities.
Hallogic® OMH3075S is a high-reliability Hall-effect sensor in the Optek portfolio, designed for non-contact switching and operation across a broad range of supply voltages. The device is specified for operation from -55 °C to +150°C, supporting applications that require reliable switching across wide temperature ranges, and is suitable for military and space applications. For applications requiring enhanced screening, B and S versions are processed and screen to MIL-STD-883, with ESD Class 3B per the same standard.
Dragonfly is a rotorcraft lander mission to Saturn's largest moon, Titan, that is designed to conduct science across multiple locations, sampling surface materials to measure their detailed compositions, and observing geology and meteorology. The Johns Hopkins Applied Physics Laboratory (APL) manages the Dragonfly mission for NASA and is building the rotorcraft, which is scheduled to launch in 2028 and reach Titan in 2034.
"Dragonfly is a mission that demands exceptional reliability and consistency, and we’re proud that the Hallogic OMH3075S has been selected for this application,” said Klaus Zwerschina, VP Components, TT Electronics. “We work closely with customers to de-risk performance-critical designs, supporting programmes that value engineering continuity and a disciplined supply approach from design-in through production, for long service life."
