Keyence FU-31 Fiber Optic Sensor, Reflective Fiber Unit
The Keyence FU-31 is a fiber optic sensing head from the FU range. Keyence catalogs the FU-31 as a reflective model. Fiber units carry light to and from the detection point so the electronics can sit somewhere accessible and protected. Applications include lead detection, fill confirmation, and presence checks inside grippers. A compatible Keyence fiber amplifier is required and is ordered separately.
