Page 43: Bar Code Scanner Pwa
Bar Code Scanner PWA The bar code scanner PWA is built inside the gripper assembly and detects bar codes between the upper and lower gripper jaws. The bar code scanner uses an IR (IR viewing scope is required to see the light) or red LED that is focused to reﬂect off the bar code label surface and converge through receiver optics on a photodetector.
