It is possible to use one sensor to capture the encoder position of the motor as it detects the leading and trailing edges of the product as it passes below the sensor. One will need to wire the sensor output to two separate high speed latch inputs on the Servopack and change the polarity of the active signal for one of them. Then use the MC_TouchProbe function block to capture the encoder positions. Finally, subtract the two captured positions to calculate the result. See the attached document for details.
