Bi-Stable Shutter Operation

How it Works

DACO advanced laser bi-stable shutter devices are pulse-driven. When the shutter receives the positive/negative pulse, the shutter moves in its “On” position, it will stay there even when the operating voltage is removed. The unit will return to the “Off” position when it receives the reverse negative/positive pulse.


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.
