DSS25 25mm Bi-stable Shutters

Overview
Since the recent introduction of the UNIBLITZ®II N-CAS® NS Series, customers have been requesting a device that
can be easily scaled for their particular application and contain no protruding actuator or other interfering components.
We have taken notice of these requests and have created our newest patent pending device, the DSS shutter series.
The DSS (Design Scalable Shutter) devices will further expand our capabilities to respond and meet the needs of our
customers.
The DSS25 is presently size and functionally compatible with the NS25B series. The DSS25 is a bi-stable shutter and
no power is required to hold the shutter in either the open or closed state. Power is required only to change the state of
the device. There are no dimensional changes associated with this configuration and it can be driven by the ED12DSS
driver board as well as the VDM1000.
The DSS series is the latest technology available from UNIBLITZ. This patent pending device has eliminated the
external protruding actuator and contains no other interfering components. All drive and damping related components
related to the mechanical motion of the shutter are contained or integrated within. The device can also be scaled for
alternate aperture sizes to further tailor the device for the most demanding customer applications.
The reliability of this device has been enhanced by containing only two unique moving parts (the drive ring and the
blades). This in conjunction with their bi-stable operation (and when driving the shutter with the new ED12DSS
+12VDC driver) has provided the most reliable device of its kind available.

FEATURES
• FLAT MOUNTING SURFACES ON BOTH SIDES OF THE DEVICE
There are no protruding components allowing flush mounting on either side of the device.
• EASILY INTEGRATED INTO CUSTOMER APPLICATIONS
Circular envelope and concentric aperture allow for easy and fast integration into customer specific applications.
• SCALABLE DESIGN
Simplicity of design allows for unprecedented ease of scaling from apertures as small as 10mm.
• LOW COST FOR A CUSTOM APERTURE
Until now a redesign for specific aperture openings of a shutter device would incur substantial NRE (Non-Recurring
Engineering) costs. The DSS shutter is specifically designed to take advantage of its versatility.
• CAN BE A REPLACEMENT FOR EXISTING FLAG SHUTTERS
Flag shutter devices are difficult to design on center and require additional offset space in a camera for the actuator.
DSS devices can be centered on aperture and hence the overall space required for a given aperture is substantially
less.
• BLADES CAN BE COATED FOR IR APPLICATIONS
DSS Shutters are particularly suited for Non-Uniformity Correction applications.
• TWO DISTINCT MOVING PARTS
The drive ring and the blades are the only parts in motion limiting points of wear.
• LOW VOLTAGE OR LOW CURRENT OPERATION
