As the demand for products in the world-market continues to push production, the requirements for high-speed automated processes capable of providing these products and components at lower cost and higher quality continues to increase. Since subjective, visual inspection techniques are clearly not conducive to highspeed inspection and control requirements, sensors have stepped in to fill this need.
One of the key components in this high-speed production environment are the sensors. These devices provide the evaluation of many features and characteristics of products at rates exceeding hundreds/second. Photoelectric sensors offer non-contact verification with far higher reliability and speed than contact techniques.
