KFU8-DW-1.D – Pulse Counter Units and Displays – PEPPERL+FUCHS Displays and Signal Processing

 316.40

SKU: KFU8-DW-1.D

Sensors used in the automation industry transmit a wide range of digital and analog signals. In many counting and control processes, these signals need to be clearly displayed, monitored, or processed. To help you find the perfect solution for such applications, we offer a wide range of counters, process displays, signal converters, and switch amplifiers that are all optimized for use with our sensors. The user-friendliness and durability of our products is always a priority at Pepperl+Fuchs.
