FT 25-BH - Detection of transparent objects

Transparent objects, such as glass or foils, absorb only a small part of the light. As a result, the difference between the amount of light emitted and received is small and switching signals can be ambiguous/inaccurate. When a standard red light sensor does not provide sufficiently reliable detection, a BlueLight sensor, like SensoPart's FT 25-BH, can be an economical and effective alternative compared to a photoelectric retro-reflective sensor or fiber-optic cable system. Compared to red light sensors, BlueLight sensors offer higher process stability for challenging materials, such as deep black plastic parts, curved objects or transparent foils.
