May 14, 2012 - Pepperl+Fuchs introduces F77 Series Ultrasonic Sensors. These miniature sensors are an ideal alternative to background suppression photoelectric sensors in dirty and dusty application environments and in applications where color variations or transparent targets are the norm. The area sensing provided by the F77 series is also ideal in applications where the pin-point accuracy of a photoelectric beam is too focused to accurately sense the target. F77 series ultrasonic sensors are 100 percent insensitive to color, provide 100 percent reliable clear object detection and ignore target holes and ridges, resulting in a coverage area that is more forgiving than that of most photoelectric sensors. This is particularly significant, for example, in a printed circuit board application where cuts and holes in the board and shiny copper tracks on a dull background would result in false readings optic-based products. These sensors are also highly immune to acoustic interference and have minimal deadband – important attributes for sensors mounted on machinery that uses numerous pneumatic cylinders. With a tiny 31mm x 11mm x 23mm housing, F77 series sensors fit in space restricted applications and provide up to 50 Hz switching frequency for fast response times. High visibility LEDs provide users with at-a-glance status indication, and simple, intuitive 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 degrees C (-14…158 degrees F). A 4-pin Nano-style M8 connector makes 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). Pepperl+Fuchs is a world leader in the design, manufacture and application of high quality factory and process automation products and services. Pepperl+Fuchs pioneered the development of proximity sensors 50 years ago, and has set the standard for innovation and quality ever since.
