“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,” says Marcel Ulrich, Product Manager. “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 miniature ultrasonic 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 31 mm x 11 mm x 23 mm housing, F77 Series ultrasonic 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.
These IP67 rated ultrasonic 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. Switch point versions are offered with either PNP, N.O. (normally open) or N.C. (normally closed) outputs. For continuous position feedback, a linear frequency output provides 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).
