Keyence FU-59U Fiber Optic Sensor, Fiber Unit Thrubeam type
FU-59U is a fiber optic sensing head from Keyence’s FU range. Keyence catalogs the FU-59U as a through-beam model. Heat-resistant, chemical-resistant, and vacuum-rated variants exist within the FU range. Fiber units carry light to and from the detection point so the electronics can sit somewhere accessible and protected. It is used for small-part detection inside tooling, nests, chutes, and enclosed mechanisms. Check bend radius limits and mounting hardware for your fixture.
