Overview


The Uniblitz DSS35B is a 35mm bi-stable optical shutter that withholds an extremely low-profile construction. The device contains no external protruding components, making it very slim and flexible for system integration. The inherent reliability of the DSS35B comes from the fact that it contains only two moving parts: the drive ring and the blades. It is guaranteed to operate for 5,000,000 operations. Bi-stable shutter devices, like the DSS35B, require no power to hold the blades in either the open or closed state.

Electronic Synchronization System


The synchronization system for the DSS35B 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 DSS35B's shutter schematic which incorporates this electronic synchronization system.

Shutter Timing


timing-diagram-white


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.
