Using a proprietary optical system, these sensors detect liquid leakage as well as the surface level of pure water or chemicals used for heat treatment, washing, or exposure processes in the manufacturing of semiconductors and liquid crystals. In addition to providing reliable detection, they save space and help to support fail-safe systems.
The optics and housing of the sensor for detecting very small parts like LEDs and of the sensor with a very narrow light beam for wafer mapping are specially designed for these applications. They not only feature a high level of detection performance, but also save space, reduce adjustment workload, and are easy to maintain.
