Hallogic sensors from TT Electronics for Nasa’s Dragonfly Mission

Specifically, it will supply Hallogic OMH3075S Hall-effect sensors for integration into fan assemblies on NASA’s Dragonfly rotorcraft mission. These support a spacecraft subsystem where reliability, and consistency, is essential across the programme lifecycle, highlights the company.

“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 of Components at 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.”

Hallogic

The Woking-based power and sensing specialist says the Hallogic devices – part of the Optek technology portfolio – are designed for non-contact motion sensing and switching. And variants processed and screened for military and space-grade applications.

In this case, the Hallogic OMH3075S is a high-reliability sensor 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, 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, TT Electronics says.

Dragonfly Mission

This Nasa mission involves a rotorcraft lander (above) on Saturn’s largest moon, that will conduct scientific experiments across multiple locations. For example, sampling surface materials to measure their compositions, and also observing geological and meteorological conditions.

The Johns Hopkins Applied Physics Laboratory (APL) manages the Dragonfly mission for NASA and is building the rotorcraft.

It is due to launch in 2028 and then reach Titan six years later, in 2034.
