Overview


Open Datasheet  DSS35B Optical Shutter Datasheet

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.


Key Features


  • 35mm aperture
  • Bi-stable operation
  • 5M1P and 5M1SM adapters included
  • Slim, low-profile form-factor
  • RoHS Compliant
  • Transfer time on opening: 23.0 milliseconds
  • Total opening time: 42.0 milliseconds
  • Configured for the VED24 Shutter Driver

Electronic Sync. Schematic:

The Synchronization system for the DSS35B 35mm optical shutter 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. See figure above for the DSS35B shutter schematic which incorporates the Electronic Synchronization system. There is no connection to the designated synchronization pins when an electronic sync. is not selected.

Note that the 5M1SM interconnect cable (shown in the electronic sync. schematic above) and 5M1P cable (bare leads for OEM use) are included with the DSS35B.

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.  




Unhoused Style

The DSS35B shutter device weighs 54.5g and is only .200 inches thick. You will notice that there are no other interfering components that will impede mounting the unit to any flat surface. It is easily mounted into an optical system via the three .090 inch diameter mounting holes (72° degrees apart) and three .095 inch diameter alternate mounting holes at the locations shown above. Presently the unit will terminate to a 2-pin JST connector (S2B-PH-SM4-TB) via a 4 inch flex interconnect.
