Plastic Fiber Type, Individual , 0.04 in. Cable Diameter, Fiber Optic Cable

Banner plastic fiber optics are an economical alternative to glass, for piping photoelectric sensing light into and out of confined areas where environmental conditions allow. Plastic fiber is ideal for applications involving small-sized object detection or repeated fiber flexing and bending. They are available in individual or bifurcated styles.

Individual Fibers: Used in pairs in the opposed sensing mode; all individual plastic fiber optics are sold in pairs. Bifurcated Fibers: 2-way, having a single sensing end that both emits and receives light and dual control sensor ends which attach separately to the sensor.
