PLC Ladder program example for Part sorting | Ladder program example for Part sorting. In this application effective products are detected and rejected from those being carried on the conveyor.
Photoelectric sensor PH1 servers as the data input to the shift register. The signal output from this sensor turns ON when a defective product has been detected otherwise it remains OFF.

Photoelectric sensor PH2 is used as a clock generator that serves as the clock input to the shift register. It generates one pulse each time the product spaced at the fixed interval from each other, has travelled a predetermined distance.
For the moment a defective product is detected by PH1 it is traced by the shift register and till the product arrives at the predetermined on the conveyor where it is rejected by the magnetic value MV.
