To signal to the assembler the next part to pick from a rack with small bins
To reduce the risk of error in an assembly operation, a one-piece EZ-LIGHT PVD pick-to-light sensor with a 400 mm range is interfaced with a process controller programmed with the correct assembly sequence. The controller makes the PVDs light up in the correct order, to show the assembler which part to pick.
After the PVD detects that the assembler's hand has entered and left the bin, the controller signals the PVD of the next bin in the pick sequence to light up.
