Operation Example
The sensor output turns ON when the sensor detects a workpiece. When the workpiece passes, the
sensor output turns OFF
. When the sensor detects the next workpiece, the sensor output turns ON
again.
The position of the encoder input is calculated based on the time stamp when the sensor output turns
ON. The difference between two positions is the distance between the workpieces.
