Radiation Tolerant Products

Class H and K Rad Tolerant

Data Bus and Motion Control Solutions

Space... the most extreme environment!
A near perfect vacuum filled with electromagnetic and cosmic radiation and subjected daily to severe temperature fluctuations.

Only electronic components of the highest quality and reliability can be used where failure can be mission-ending and repair is not an option.

Only DLA certified MIL-PRF-38534 Rad Tolerant components to Class H and Class K (highest level) process are engineered, manufactured, and qualified to be used in this environment.
