Plastic optical fibers use the same photoelectric sensing modes as sensors (diffuse reflective, through-beam, retroreflective). The two types of fiber-optic assemblies that are used with these sensing modes are bifurcated (reflective) and individual. •Reliabledetection, positioning of small transparentvialsandflasks The challenge: •Precise,responsiveand repeatable •Hygienicdesignrequired •Sometimessmallspace requirements The solution: •WL4Ginhygienicdesign •WLL180 Food industry The task: •Count,detectandposition packagedfoods The challenge:. The following is a classification example of KEYENCE's fibre units (FU Series). Threaded for easy mounting onto brackets and machine equipment. The transducer modulates a parameter of the optical fiber system, such as intensity, wavelength, polarization, or phase. These sensors stand out for their small size, immunity to electromagnetic interference, and capability to function in. A fiber optic sensor and two fiber optics made of plastic or glass fibers make up a fiber optic system. The generated light is guided through an optical fiber (transmission path) to the object to be. The DR-Q digital laser transparent object sensor monitors overlapping transparent containers. Generally, detection is based on height.
