where spatial limitations are a consideration).
Mechanical Specifications

Uni-stable shutter devices, like the CS35, require
power to hold the blades in the open state.

Under no circumstances should any type of lubricant be applied tothe shutter blade area. Lubricating the shutter blades will likely slow
the shutter down and may eventually render it inoperable.

Electronic Sync.

5-PIN

CONNECTOR

The electronic synchronization system provides afeedback signal (through the driver utilized) after
the shutter transfers to the open state. The system
incorporates an infrared emitting diode, an infraredsensitive detecting transistor, and an interruptingvane. The vane is attached to the shutter so as toblock the light path between the emitter and detector
in the closed position. When the shutter transfers
to the 80% open position, the vane is removed fromthe infrared light path, allowing the emitter to switch
