NS35B 35mm Optical Shutter
$665.00 – $1,350.00
Current Lead Time: 4 – 5 weeks
Description
Current Lead Time: 4 – 5 weeks
The Uniblitz NS35B is a 35mm-aperture bi-stable optical shutter utilizing our patented N-CAS® technology. The NS35B’s simple design provides maximum clearance around the aperture, and a machined flat surface makes for its easy integration into virtually any system. The NS35B has an overall diameter of 3.18 inches, and an electronic synchronization is available.
Bi-stable shutter devices, like the NS35B, require no power to hold the blades in either the open or closed state.
Key Features
- 35mm aperture
- Bi-stable operation
- Only two unique moving parts
- Slim, low-profile form-factor
- RoHS Compliant
- Transfer time on opening: 12.0 milliseconds
- Total opening time: 18.5 milliseconds
- Can be configured for the VED24, VDM1000, or ED12DSS shutter drivers.

3 (Continuous/Burst) Continuous frequency rating specified at shutter’s minimum exposure pulse. Burst frequency rating specified for four (4) seconds maximum with one (1) minute minimum between bursts.
Electronic Synchronization System
[columns][span7]The synchronization system for NS shutter devices incorporates a small magnet mounted to the driving mechanism and a Hall effect sensor. When the device achieves approximately 80% of full open, the magnet causes the Hall effect sensor to change state, producing a signal to indicate that the shutter has switched to the active state. Shown to the left is the NS series shutter schematic which incorporates the electronic synchronization system. There is no connection to the designated synchronization pins when an electronic sync. is not selected.

Shutter Timing
[columns] [span5]
The question regarding enhancement of shutter speed with the application of user supplied lubricants has been repeatedly asked. It is our experience that lubricating the shutter blades will actually slow the shutter down and eventually render the shutter inoperable. Under no circumstances should any type of lubricant be applied to the shutter blade area.
