Better safe than sorry—even if the power supply fails!

Whenever the application requires a defined position in the event of a power supply failure, an actuator with an integrated fail-safe spring comes into consideration.  Thanks to the patented combination of a smooth-running worm gearbox with a specially developed spring, we achieve very low current consumption in modulating duty coupled with a compact design. Thanks to the proven modularity of validated designs, we can also get your application ready for series production quickly.
