Keyence FU-78 Fiber Optic Sensor, Fiber Unit Thrubeam type
FU-78 is a Keyence FU series fiber unit used with a separate fiber amplifier. Keyence catalogs the FU-78 as a through-beam model. 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. Verify amplifier compatibility before treating this as a direct swap.
