Pepperl+Fuchs' F77 Series Ultrasonic Sensors are an alternative to background suppression photoelectric sensors
Pepperl+Fuchs' F77 Series Ultrasonic Sensors are an alternative to background suppression photoelectric sensors in dirty and dusty application environments and in applications where color variations or transparent targets are the norm. These sensors are designed to be immune to acoustic interference and have minimal deadband. F77 Series sensors are made to fit in space-restricted applications and are made to provide up to 50 Hz switching frequency. LEDs are engineered to provide users with at-a-glance status indication, and range adjustments make it easy to adapt to changing needs on-the-fly. These IP67-rated sensors are rated for use in temperatures ranging from -25-70° C (-14-158° F). A four-pin Nano-style M8 connector is built to make installation easy. These sensors provide one PNP, N.O. (normally open) or N.C. (normally closed) switch point output, use inexpensive discrete PLC inputs, offer high or low frequency options and deliver a 2 Hz/mm maximum resolution. They are available in diffuse (up to 400 mm sensing range), retroreflective (up to 400 mm sensing range) and thru-beam models (up to 800 mm sensing range).
