ID Flag Sensors (V680-HAM91/-HAM81)

Calculation Example

Read Processing Using Combination of V680-D1KP66T and V680-HS63

Note: 1. The travel speed depends on factors such as the communications distance Y and axis offset. Therefore, it is recommended to refer to

the interrogation zone figure and to perform operation using the widest part of the area.

2. The calculated value is a rough guide.

Perform testing with the actual devices before actual operation.

3. This calculation formula does not include communications error processing.
