Fiber Optic Amplifiers

Teach-in button eases parameterization

Pepperl+Fuchs GmbH

Allowing speedy commissioning, the SU18 and SU19 fiber optic amplifiers from Pepperl + Fuchs feature versatile application options and economic operation. For device parameterization, it is merely necessary to correctly position the object that is to be detected and press the teach-in button. The intelligent fiber optic sensors then adjust such settings as switching thresholds and optimum amplification for the detection of small parts, and so on. On the standard SU18, the user can switch between standard, high resolution and high speed mode by DIP switch, so that even the detection of the most minimal contrast and particularly fast moving objects are supported. A highlight of the SU19 premium model is the high-resolution, 4-digit percentage display, which is able to provide a percentage indication with decimals, for example switching threshold values of 100.0% and stability control values of 150.0%. Other special features of the premium model include back panel wiring via plug-in jumpers and a special operating mode for the detection of transparent objects. The SU18 High-Power has an additional “High-Power” operating mode and is characterized by particularly long sensing ranges. In applications with typical sensing ranges and also the presence of soiling, the SU18 increase functional safety.  The device can be used where only higher-performance devices could previously be employed and 7-segment displays can also be dispensed with.
