Detection of PCB's and electronic components in conveying systems can be performed with a high degree of accuracy using the PD30 IO-Link smart sensors; particularly optimized for small object detection is the PD30 with point-spot light source for the measurement up to 6 meters distance. The predefined and selectable application functions like speed and length, pattern recognition, divider and object and gap monitoring, provide the customer with additional data and decentralized controls to optimize the production process and enable predictive maintenance. For some specific applications in semiconductors, the PD30 is also available with an IR light source.
