4.8. Typical Performance
The time it takes to open the shutter or close the shutter (IA and DE as shown in
Figure 5) are constant characteristics of the device. The time delay for both
opening and closing is a result of the time it takes to energize the coils.
The net effect is the delay from the initiation of the starting pulse to the shutter
responding (IA) is typically 3.3 ms. Similarly, the closing time (DE) is typically
2.6 ms.
The mechanical rise time of the shutter is given as AC in Figure 5. The fall time is
given as EG. The typical values for the rise and fall times are 3 ms with a maximum
time of 4 ms.
Therefore, the total time it typically takes for the shutter to open would be IC or
6.7 ms. The total time it typically takes for the shutter to close would be DG or
6 ms. Depending on your application, some or all of these values are important to
note.
