Burst frequency rating specified for four (4) seconds maximum with one (1) minute minimum between bursts.

## Electronic Synchronization System 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.
