The Pepperl+Fuchs flat subminiature F79 sensor (16x8x4 mm) is used in a feed conveyor during the manufacture of printed circuit boards (pcb). The sensor monitors the stopping mechanism at the feed system to prevent any congestion and accidental collisions. With the very tight space conditions in the feed conveyor, the miniature F79 sensor is the perfect solution to ensure the safe and reliable operation of the pcb manufacturing production line.
