Spring Shutter Operation

How it Works

DACO advanced laser spring shutter devices are designed to move to the energized position when it receives operating voltage. The unit will remain in that position while the voltage is applied. When the voltage is removed, the shutter comes back to its de-energized state.


DACO’s core focus is to provide customized solutions — all built to the most exacting client specifications. Below are sample specifications ranges for models that we manufacture. So if you don’t see what you’re looking for, contact us for more information.
