The FU-7F(10000) is a high-performance fiber unit, manufactured by Keyence, that is used for fiber-optic distance measurement. It is capable of measuring up to 10,000 mm (100 m) with a resolution of 0.1 mm, making it a highly accurate and precise instrument. The FU-7F(10000) uses a blue LED light source and a photodiode to determine the length of a fiber linkage, which is measured by passing light down the fiber cable. The measurement range of the FU-7F(10000) covers distances of 0.1 to 10,000 mm and can be mounted on a variety of surfaces and angles to provide enhanced versatility. The FU-7F(10000) is very durable, with a rated IP67 ingress protection rating, and is built to withstand harsh environments. The unit is also very easy to install and operate with minimal setup time.
