Key installation points

Applications with round, metal targets are difficult for sensors due to issues with glare and surface finish. However, these sorts of applications can be performed easily with the IV2 Series. By using the Outline Tool, stable detection is achieved even if there are differences in surface condition from one part to the next. Furthermore, the OK/NG image history can be saved together with the detection date and time.
